Role of Physics in Engineering

If you are interested in building your career in Engineering, then studying physics is obvious. We cannot imagine our life without Physics. The future technology directly or indirectly is related to physicists who have made a huge contribution to the world. 

Engineering is a profession in which scientific knowledge and mathematics is used for innovations, to develop new things that benefit mankind, which is important to society and nature, making everything around us easier.

Engineering is the mindset to think over the use of scientific principles, to design and build machines, structures, and other items. Engineering enables us to think out of the box.

Basic sciences have their own importance in the broad spectra of the engineering education system.  Knowledge of science helps the engineer understand the constraints inherent in a problem and helps the engineer develop possible approaches for a solution. Now let’s throw some light on the role of physics in engineering.

Role of Physics in Engineering

Physics is one of the most fundamental scientific disciplines, and its main goal is to understand how the universe behaves. Physics generates fundamental knowledge needed for the future technological advances.

Study of physics develops the ability of Problem Solving, Logical Thinking and also the Ability to think intellectually.

Physical concepts, such as Classical mechanics, Thermodynamics and Statistical mechanics, Electromagnetism, Quantum mechanics, Atomic physics, Molecular physics, Optics, Condensed Matter Physics, Nuclear Physics etc., play a vital role in the process of innovation, which is, crucial in the development of engineering branches.

Engineering is basically physics applied to create something more practical. It can be mechanical, electrical, civil, etc., but they’re all basically governed by physics. There’s no way you would solve complex engineering problems without understanding the physics behind it.

In Civil Engineering, the laws of physics can tell you about forces, tension, harmonic vibrations and oscillations, tensile strength, elasticity, and all kinds of other concepts that you can use to make calculations about your designing and construction work .

For every subject of Mechanical Engineering, you need the help of physics in dealing with aircraft, watercraft, engines, robotics, weapons, cars, pneumatics, hydraulics and others by using core areas including mechanics, dynamics, thermodynamics, materials science, structural analysis, and electricity.

Electrical engineering involves designing electrical circuits including motors, electronic appliances, optical fiber networks, computers, and communication links. Electrical engineers often need to convert electrical energy to other forms of energy, with the understanding of mechanics and thermodynamics. Knowing the fundamentals of Electrical Engineering, in addition to, how small-scale components like integrated circuits and various types of transistor logic, all functions require at least an intermediate understanding of Electromagnetism, which you learn from Physics.

Electronics include the workings of transistors, diodes and semiconductors.  Integrated circuit uses physics to study how various tiny transistors are connected in circuits. Electromagnetism is used for antennae design, RF signals, wireless communications, etc. The field of robotics relies on a lot of things physics such as dynamics, chaos, mechanics, motors, etc. as well as optics (for cameras for computer vision).

Since Electrical engineering leads to Electronics engineering and finally to Computer engineering & Information Technology and Artificial Intelligence, it can be concluded that the mother of all engineering branches is Physics.

An engineer might design the product itself, or just figure out a way to build it. But either way, success is impossible without an understanding of the physics behind each of them.

Thus, it is true that Physics has a significant role in Engineering.

I conclude with a quote from the Missile Man of India, Dr. A. P. J. Abdul Kalam, “Teaching is a very noble profession that shapes the character, caliber, and future of an individual. If people remember me as a good teacher that will be the biggest honor for me.”

Role of Ethics in Engineering

Engineers are the strong upholders of the nation. They deal in things that are as important as laying the foundation of a country. An Engineers work/art has a compelling impact on the society, let alone the people, leading them in doing an adept work with utmost commitment to self and to the society. The commitment and adeptness thus demands no carelessness as, many lives depend on their work. To get a clear picture, we can say that a bridge build with low quality raw material, might fall down, endangering thousands of people’s life. This is wherein the deeds of righteousness emerge, the ability to act with lot of diligence and care. Working on ethics is thus an integral part of these deeds and acts. In the words of great Albert Einstein, “I do not believe in immortality, and I consider ethics to be an exclusive human concern with no superhuman authority behind it.” Ethics are based on well-founded standards of right and wrong that prescribe what humans ought to do, usually in terms of rights, obligations, benefits to society, fairness, or specific virtues, where engineers are no less. ‘Engineering ethics’ in this way finds its way up to the ladder of moral consciousness/self-righteousness.

Engineering Ethics

How do the guidelines of Engineering Ethics actually work? We can say that Engineering Ethics are the primary obligation of any engineer to protect the safety, health and the welfare of the people. In a professional scenario, we are placed in a huge threshold of either doing what’s safe for the people or blindly following the orders of the employer. This crossroad situation consequently gives rise to the discussion about 'Engineering Ethics'. According to Martin At El, ‘‘Engineering Ethics relates to the study of the moral issues and decisions confronting individuals and organizations involved in engineering”.  They are underlying in itself the questions about moral conduct, character, policies, relationships and corporations involved in technological activities.

Now, where does need of studying Engineering Ethics originate? Considering that we all are living in an age of highly advanced technology and in this mind boggling and physically tiring race of reaching the vertex of success, we take such decisions that may not only have unintended consequences but are also adversely affecting the society.

Another reason is that while performing our professional duties, there may arise such situations which may lead to conflicts between our Personal and Professional interests. For instance, one is working in a reputed construction company where the material that company uses is of poor quality that could not be used for constructing of dams, then one is in a state of dilemma of ‘what is to be done?’, if the material is overlooked, thousands of lives would be in danger and if voice is raised against it, one may lose his/her job. The example reflects the situation of many people who have conflicts arising between personal and professional interests, and thus answering our question about why do we need to study engineering ethics.

To have much clear perspectives on code of ethics of engineering many Professional societies such as AAES, ABET, NSPE, IEEE, and AICTE have framed certain codes which are extremely handy for them by administering guidelines to be taken care of while executing their professional responsibilities. Some of the Ethics which Engineers have to follow are listed below.

Engineers, in the fulfillment of their professional duties, shall:

  1. Hold paramount the safety, health and welfare of the public.
  2. Perform services only in areas of their competence.
  3. Issue public statements only in an objective and truthful manner.
  4. Act for each employer or client as faithful agents or trustees.
  5. Avoid deceptive acts.
  6. Conduct themselves honorably, responsibly, ethically, and lawfully so as to enhance the honor, reputation, and usefulness of the profession.
These are the code of ethics which are more or less universally followed.

You as an Engineer!

As an engineer you may also have to make many decisions when you have to be clear about what is right and what is wrong, and it is here that the code of Ethics will guide you, you can also design your own code of ethics and follow it to fulfill your Professional responsibilities.

Shared below are the guidelines which will help you in taking the right decisions:-

Test your decisions in the following manner:

  • Is the decision good for all?
  • Does it protect the health of the users or the public in general?
  • Is it harming the environment?
  • Is it energy efficient?
  • Is it in the interest of the nation?
  • Have you taken into consideration all the stakeholders as well as the people who are directly and indirectly affected by it?
  • Is it able to justify prescribed standards and has efficiency?
  • Is it affordable by a common man?

Actually, these codes make one feel really responsible and proud to be a professional, thus motivating towards the commitment one should have towards one’s profession. This self-made code of ethics will provide the necessary moral support and guidelines, which will inspire you to work with great commitment and more effectively serve the public. It can also win you greater powers of self-regulation for the profession itself, while lessening the demand for more government regulation.

Internet of Things (IOT): Need of Future

What is IOT?

The Internet of Things (IoT) is a system of various physical devices which are interrelated, connected with each other through internet and are capable enough to collect and transfer data over a wireless network without human interference.

Internet of Things

How IOT works?

IoT devices include sensors, processors and mini-computers which are connected to Internet and execute on the data collected through various wireless sensors with the help of machine learning. Machine learning is a type of Artificial Intelligence (AI) that helps the computer or system to learn, collect data from their environment and provides ability to improve from experience without any prior programming. IOT devices are more susceptible to virus, malware and hacking.       

                                                                                                                           

Architecture of IOT

IoT architecture is the combination of various elements such as sensors, actuators, cloud services, and layers. Internet of Things architecture layers are segregated in order to manage the working analytically. The planning of all constraints is mandatory before IoT architecture working starts. Majorly, IoT architecture consists of:

1. The client side which is comprised of IoT Device Layer

2. Operators on the server side i.e. IoT Gateway Layer

3. A pathway for linking clients and operators i.e. IoT Platform Layer


Main Stages in the IoT Architecture

1. Sensors and actuators

2. Data Acquisition Systems and Internet gateways

3. Edge IT

4. Data centre and cloud.


Stages of IoT architecture

Stage 1: Wireless sensors and Actuators

Sensors have ability to convert acquired information into data which may be further used for analysis. Wireless sensors include embedded systems such as RFID tags, readers and other sensors which are used to collect and transfer information. Actuators have ability to sense physical reality eg. Switching off of the equipments and sensing of temperature.

 

Stage 2: Data acquisition system & Internet Gateway

Data which is sensed and collected is raw one and also contains unwanted database. Data acquisition is nothing but sampling the physical real time conditions. Data acquisition systems convert analog data into digital values for processing. The Internet gateway receives the data in digitized form and with the help of Wi-Fi, wired LANs, or the Internet systems, transfers it further to process.

 

Stage 3: The appearance of edge IT systems

Edge IT systems perform improved analytics and pre-processing with the help of machine learning and visualization technologies. Even with this further processing may happen prior to the stage of the data centre. Stage 3 is closely correlated to the previous Stages in the building of architecture of IoT. The position of edge IT systems is close to the sensors and actuators, creating an electric wiring.

 

Stage 4: Analysis, Management, and Storage of data

The data centres are talented enough to analyze, handle, and store huge amounts of data. It is also much more secure to store it here.

 

Applications of IoT

  1. Smart Home Applications
  2. Health Care
  3. Smart City
  4. Agriculture
  5. VANET

Engineering College and Alma Mater Connect

The involvement of alumni in supporting and providing contributions voluntarily to the engineering and management colleges is important for maintaining and expanding the development of a college.

JD College of Engineering and Management has started JD Alumni association. It has opened a new avenue for the growth, development and strong bonding with the institution. Hence, this is a potential for all alumni to contribute to the college in different ways and scale.

Cycle of Success

Role model and inspiration

Alumni are an effective role model and can be easily accepted by students. With the return of the alumni to support Engineering Colleges, they bring with them credibility and justification as part of a successful college. Experiences shared by the alumni with students whether in time management; financial management; development of self-discipline and character, or in career management serve as guidance and inspiration for students.

Career mentor

Competition in entering the workforce is becoming more intensive as a result of a higher number of graduates getting degree from colleges compared with a limited number of job opportunities. In the final year of their studies, students must identify seriously their career prospects. Therefore, alumni can be a reference for the faculty concerned in meeting the needs of students and graduates in obtaining work in selected fields.

Providing expertise

Besides that, the alumni can contribute by providing sharing their expertise in their occupation in developing new study programs at their respective college. Alumni can contribute as a guest lecturer, advisor in committees, industry experts and cooperative partners in projects with the College/university. This will improve the development of their alma mater.                                      

Opportunity to access professional development

When the alumni community is successful and obtains recognition from the corporate world, industry and the wider community. It can potentially create a stronger network as well as trust in the respective college. Also, they will assist younger alumni from the college/university to access opportunities in improving their careers and professionalism.

 

Conclusion

A good combination of the above-mentioned approach based on your institution’s vision will make your alumni feel part of their alma mater and motivate them to stay connected forever.

Alumni engagement should not be just about class reunions conducted once every year. If it has to be a long-lasting association based on trust and affection then the relationship must extend beyond seasonal events.

Simply spending time and money on engaging alumni through events will not serve any good. Colleges should come out with innovative ideas to bring alumni onboard. For achieving this, colleges are creating a culture of building a support system for its alumni network. This support system will then act as a propellant to fuel organic bond between the alumni and the college that will remain alive always.

Digital Learning - A Novel Approach for Education

The traditional teaching has been totally shifted to student centric. With the invention of technology and with its usage at high level, the expectations of delivering the teaching contents have been changed. This paradigm shift is the digital learning, which has emerged as a boon for everyone, especially the environment. It is the internet, which has brought a drastic change in the perspective of human beings and brought about a revolution in everything.  Digital learning is the small aspect of that revolution. 

Digital Learning- A Novel Approach for Education

The digital learning plays a vital role in upgrading the overall aspects of classroom. Nowadays, the students are more techno-savvy and in order to cope up with the expectations of students, one must have the learning skills of digital world. There are so many apps freely available for digital learning, and it is the requirement of time. The days are gone wherein we had traditional teaching pattern, now everything is digitalized and hence the education also. Few months back, there was reluctance in using digital learning methodology for education and now the pandemic has bound us to use it at the fullest. Nobody had predicted that people in education sector will be using different applications for teaching. A digital classroom is a teaching and learning environment where students can study, learn, gain and grow through an online medium. Education technology and Electronic learning have emerged as a boon for education sector and certainly it is going to redefine and reform the face of Indian education system in all aspects with innovative prospect and expertise as whole.

Within a digital learning concept, teachers and students can not only exchange words, but also view and discuss case studies and presentations. This is the only medium of education which allows aspirants to participate virtually and connect with resources in groups. With this intent, so many universities have started the digital learning. Earlier the students were deprived of getting the knowledge if they missed any class, now e-learning has surmounted all these problems.  

This paradigm shift is firmly whispered to be highly productive, prolific and enhancing the eminence of teaching-learning along with breaking the biological obstruction for acquiring the quality education. The e-learning is the most recent and hottest inclination in the education sector. Earlier, when technology was not a part of education system, paper, notebooks, chalks and green boards were only tools for education.

It is not only the universities which provides e-learning but many educational sites have come up with the contents which are highly required for the students.  The main advantage of digital learning is the saving of precious time and is highly environment friendly. As the digital learning does not require any paper and this has stopped the cutting of large chunk of trees. With the innovation of IOT and other technologies, the education becomes more effective and user friendly where one can learn anything on a click of mouse.

Aeromodelling: Let your Dreams, Take Flight

Aeromodelling can be the first step for venture into the field of UAVs (Unmanned Aerial Vehicle), which has numerous engineering applications such as video surveillance, intelligence, remote sensing etc. It is an amazing module for self articulation, which leads the person to a successful career as a Pilot, Aircraft Designer, Aircraft Maintenance Technician, Aero-Space Engineer etc.

Aeromodelling

What is Aeromodelling?


Aeromodelling involves the activities such as design, development and flying of small air vehicles. The objects such as Radio Controlled Aircraft, Ornithopters (a machine that flies by flapping its wings), paper planes, etc. are contained in the modeling. We can learn, relate the concepts of science and engineering principles. It helps to understand all the fundamental principles of Flight, how and why an aircraft flies. 


History of Aeromodelling

Aeromodelling activity was started in the nineteenth century by Dr. Thomas Young. He discovered the lifting property of cambered surface in comparison to flat surface.


Streams involved in Aeromodelling

Aeromodelling involves a lot of interdisciplinary concepts of various engineering streams such as Mechanical, Electrical, Aeronautical, Electronics, and Computer Science, but majorly it involves Aerospace/ Aeronautical engineering topics.

Types of Aero Models

There are two types of aero models: Powered Models and Unpowered Models.

Powered Models: The powered models can fly with the help of engines and propellers. Most of the flying models can be categorized into groups.

  • Free flight (F/F) model aircraft fly without any method of external control from the ground.
  • Control line (C/L) model aircraft use cables leading from the wing to the pilot.
  • Radio-controlled aircraft contains a transmitter operated by the controller, sending signals to a receiver in the model which in turn actuates servos. Servos manipulate the model's flight controls in a similar manner to a full sized aircraft.

Propellers: Powered aero models, including electric, internal-combustion, and rubber-band powered models, generate propel by rotating an airscrew. Propeller is commonly used to generate force due to the angle of offensive blades, which forces air backwards. Due to this, the plane moves forward.

 

Unpowered models: The unpowered models are operated without any engines.  They can remain flying for a specific period of time without committed force. They can be classified as fixed-wing gliders, lighter-than-air balloons and tethered kites. Parachutes require a route, not just a vertical drop. Due to powerless gliders, flight persists through exploitation of natural wind in the surroundings. 

 

Aero Models used in Advertising

Many airlines permit their aircraft models for promotional uses. These include Delta Air Lines, Air France, British Airways, Avianca, Aeroméxico, FedEx, Polar Air Cargo, Air New Zealand, Qantas, Singapore Airlines, United Airlines, South African Airways, Finnair, American Airlines,  Lufthansa, Japan Airlines, Royal Jordanian, Korean Airlines, and Asiana Airlines, etc. 


Benefits of Aero Modeling

Aero modeling helps to improve hand and eye coordination, understand the importance of team work, learn to cope with success and failure, create 3D objects, learn to work with plans, use hand tools etc. Also it gives immense feel of Achievement, High Confidence & Self Esteem. It ignites the Right-Brain Activity and promotes better learning. It helps to improve Logical Reasoning Capabilities of the person. Youngsters can be educated to an exciting field of science that trains them to live a life full of Thrill & Excitement and to become a role model for others in their community.

 

So, Aeromodelling has a lot to offer for the technocrats with the desire to sharpen their multi-disciplinary skills and apply them. And unlike the trendy conviction, Aeromodelling is not just for faddy flyers!

Powering India: Insight into Electrical Engineering

The power sector in India is mainly governed by the Ministry of Power. There are three major pillars of power sector; these are Generation, Transmission, and Distribution.

 

As far as generation is concerned, it is mainly divided into three sectors; these are Central Sector, State Sector, and Private Sector. 

Central Sector or Public Sector Undertakings (PSUs), involved in the generation of electricity include NHPC Ltd., NTPC Ltd. and Nuclear Power Corporation of India (NPCIL). Besides PSUs, several state-level corporations such as Maharashtra State Electricity Board (MSEB), Jharkhand State Electricity Board (JSEB), Kerala State Electricity Board (KSEB) etc are involved. Other than PSUs and state level corporations, private sector enterprises also play a major role in generation, transmission and distribution. The Power Grid Corporation of India is responsible for the inter-state transmission of Electricity and the development of National Grid.

India’s power sector is one of the most diversified in the world. Sources of power generation range from Conventional sources such as Coal, Natural gas, Oil, Hydro and Nuclear power to viable Non-conventional sources such as wind, solar, and agricultural and domestic waste.  Over the past decades, energy demand has steadily increased across all sectors including agriculture, industry, commercial and residential, and is expected to continue to grow.

In order to meet the increasing demand for electricity in the country, massive addition to the installed generating capacity is required.


Powering India: Insight into Electrical Engineering

The total installed capacity of power stations in India stood at 368.68 Gigawatt (GW) as of January 2020.  Around 750 million people in India gained access to electricity between 2000 and 2019, reflecting strong and effective policy implementation. Increased access to affordable energy has raised the living standards of all segments of the population.   Government of India is pursuing a very ambitious deployment of renewable energy, notably solar, and has boosted energy efficiency through innovative programmes such as replacing incandescent light bulbs with LEDs (under the Ujala scheme).

The development of technology and innovation will be a key driver for India’s economic growth. The Government of India has identified power sector as a key sector of focus so as to promote sustained industrial growth.  The Government of India’s focus on attaining ‘Power for all’ has accelerated capacity addition in the country. 

Some initiatives by the Government of India to boost the Indian power sector are:

  • The Union Budget 2020-21 has allocated Rs 15,875 crores to Ministry of Power and Rs 5,500 crores towards the Deen Dayal Upadhyay Gram Jyoti Yojana (DDUGJY).

  • The Government of India has released its roadmap to achieve 175GW capacity in renewable energy by 2022, which includes 100 GW of solar power and 60 GW of wind power.

  • Coal-based power generation capacity in India, which currently stands at 229.40 (As of October 2019) GW is expected to reach 330-441 GW by 2040.

  • All the states and union territories of India are on board to fulfill the Government of India's vision of ensuring 24x7 affordable and quality power for all as per the Ministry of Power, Government of India

Some major investments and developments in the Indian power sector are as follows:

  • In December 2019, NTPC announced investment of Rs 50,000 crores to add 10GW solar energy capacity by 2022.

  • ReNew Power and Shapoorji Pallonji will invest nearly Rs 750 crores in a 150 megawatt (MW) floating solar power project in Uttar Pradesh.
