Mechanical Engineering vs. Electrical Engineering

These two branches of engineering are so famous and high in demand that every engineering student wants to know that which among these two is better? Both of these branches of engineering are high in merit in all universities all over the world. It’s really hard to choose one which is better among these two disciplines. I interviewed almost fifteen mechanical and electrical engineers before writing about this issue. Those who were mechanical engineers, they said mechanical engineering is better while those who are electrical engineers, they said that electrical engineering is better. 

So Mechanical engineering vs Electrical engineering – the debate goes on.

Here I would like to present a more logical difference between these two disciplines of engineering and I hope it will help all young students and prospective students to get to know about these two branches of engineering. Because in the end, I personally think it’s someone’s interest which makes him/her choose between mechanical or electrical engineering.

Actually ME and EE are near polar opposites in the engineering world. ME is based on the mechanics field of physics, while EE is based on the electricity and magnetism field of physics.

I have made things quite simple here. If you love solving problems in Mechanics portion of physics then definitely mechanical engineering is for you and if you feel attraction in solving problems in electricity and magnetism then electrical engineering can be a right choice for you. Mechanical Engineering takes you towards things involving machines, mechanisms, physics (forces etc.), manufacturing and production, liquids, gases and more tangible things. While on the other hand, Electrical Engineering takes you towards things involving power, cabling, fuses, electrical appliances production, circuits, semiconductors and generally electricity and energy management and application in a larger scale.

Let us be more practical and look deep into future. Being a mechanical engineer you will learn to build car’s body and engine while being an electrical engineer you will be able to handle/build/manage the car's battery.

Above discussion was dealing with the debate of Mechanical engineering vs Electrical engineering on educational basis and basic differences in their structure. Talking about career opportunities, jobs and pay differences, I will keep things straight for you. In this modern world, you will never be paid higher or lower based on your qualifications. Believe me it’s so true in this world these days. You are paid based on your technical knowledge and experience which you get. So don’t worry about job and pay at this stage. Just choose that branch of engineering which you find interesting. It will help you to do more and learn more within circle of your interest.

I hope this article will help you solve this historical engineering puzzle of Mechanical engineering vs Electrical engineering. Now decision is all yours. Choose wisely because this will be a life time decision for you. You are going to define your future so define it wisely. Don’t forget to leave your comments if you need any help and to learn more.

Types of mechanical engineering

Many students keep asking us about different types of mechanical engineering. They are not clear about different areas of mechanical engineering. Actually this question is a bit confusing in itself. We call it“sub disciplines” instead of “types”. So “Types of mechanical engineering” actually are “sub disciplines of mechanical engineering” in a true sense. All different types of mechanical engineering have something in common which is study and application of heat and motion. Here are some of the well known types of mechanical engineering (or sub disciplines in other words):

Manufacturing engineering:  Manufacturing engineering is a type of mechanical engineering which deals with study and analysis of different manufacturing practices. It deals with research and development of machines, machine tools, parts, products, equipment, processes and systems etc.

Thermal engineering: As the name suggests thermal engineering deal with cooling and heating of processes, closed environments or equipment etc. Mechanical engineers in this area of specialization are taught to keep any system at optimum temperature.

Automotive or Automobile engineering:  Automotive engineers design, build, maintain, and operate self - propelled vehicles for use on land or sea, in air or space. From manufacturing of car parts to assembly of car parts, all is covered under umbrella of automobile engineering. This is one of the most interesting and most demanding types of mechanical engineering.

Acoustical engineering:  Acoustical engineers manipulate and control vibrations and they work on reducing unwanted sounds in any system or process.

Aerospace engineering: In this branch of mechanical engineering, students are taught things like design, construction, operation and support of aircrafts, spacecrafts and other air vehicles. They are responsible for the research, design and production of spacecraft, aircraft, aerospace equipment, missiles and satellites.

Naval Engineering:  This is one of the types of mechanical engineering which deals with marine structures. Naval engineers are responsible for design, analysis, maintenance and manufacturing of marine vehicles and other related structures.

Biomedical engineering: Biomedical engineers study both the fundamentals of mechanical engineering and human anatomy and physiology.  They design and develop biomedical products and products which help people with different injuries like spinal injuries etc. This is one of the best types of mechanical engineering which is serving medical field in a very positive way. Many human disabilities can now be recovered due to the efforts of biomedical engineers.

Structural analysis: This is a branch of mechanical engineering as well as civil engineering. Students in this branch try to learn how and why structures fail and what possible measures are to e taken to save any structure from failing.

I hope after reading this article, you will be able to understand all basic types of mechanical engineering. These sub disciplines as mentioned above are very fundamental and basic areas of specialization for mechanical engineers. All these fields include study of basic mechanical engineering concepts and then at later stage students are encouraged to opt for their areas of interest.

Air Brake (road vehicle)

Air brakes or more formally a compressed air brake system is a type of friction brake for vehicles in which compressed air pressing on a piston is used to apply the pressure to the brake pad needed to stop the vehicle. Air brakes are used in large heavy vehicles, particularly those having multiple trailers which must be linked into the brake system, suchas trucks, buses, trailers, and semi-trailers in addition to their use in railroad trains.

Supply system:-
The air compressor is driven by the engine either by crankshaft pulley via a belt or directly from the engine timing gears. It is lubricated and cooled by the engine lubrication and cooling systems. Compressed air is first routed through a cooling coil and into an air dryer which removes moisture and oil impurities and also may include a pressure regulator, safety valve and a smaller purge reservoir.
Advantages:-
Air brakes are used as an alternative to hydraulic brakes which are used on lighter vehicles such as automobiles.Air brakes have several advantages for large multitrailer vehicles:
1). The supply of air is unlimited, so thebrake system can never run out of its operating fluid, as hydraulic brakes can. Minor leaks do not result in brake failures.
2). Air line couplings are easier to attach and detach than hydraulic lines; there is no danger of letting airinto the hydraulic fluid. So air brake circuits of trailers can be attached and removed easily by operators with no training.
3).Air not only serves as a fluid for transmission of force, but also stores potential energy. So it can serve to control the force applied.
4).Air brake systems include an air tank that stores sufficient energy to stop the vehicle if the compressor fails.
5).Air brakes are effective even with considerable leakage, so an air brake system can be designed with sufficient "fail-safe" capacity to stop the vehicle safely even when leaking.

Honda develops new technology to weld steel and aluminum together

Although some engineers have had success in spot welding steel and aluminum together, it has largely been considered impossible to achieve reliable, continuous welds directly between the two dissimilar metals. 

That changed last Thursday, however, when Honda Motor Company announced that it has devised a technique for doing that very thing. The results, which include lower vehicle weight and better performance, can be seen in the 2013 Accord.

The Honda team developed a variation on Friction Stir Welding, in which metals are joined via mechanical pressure – it's the same technique that has been used for experimental steel/aluminum spot welds in the past. As Honda explains it, “This technology generates a new and stable metallic bonding between steel and aluminum by moving a rotating tool on the top of the aluminum which is lapped over the steel with high pressure.” The welds that result are reportedly as strong or stronger than those made using regular Metal Inert Gas welding.

Steel/aluminum subframes built with the new technique are said to be 25 percent lighter than those made entirely out of steel, which should translate into improved fuel economy. The process also made it possible to alter the structure of the subframe, so that the mounting point for the suspension could be relocated – this change has reportedly increased the rigidity of the mounting point by 20 percent, and thereby improved the car’s dynamic performance.

Additionally, the new process uses about half the amount of electricity as Metal Inert Gas welding, and the machinery it requires isn’t as large as that traditionally used for Friction Stir Welding – in fact, it can be attached to an industrial robot. The technique can also be used for aluminum-to-aluminum welding, without any hardware changes.

A new non-destructive inspection system, incorporating an infra-red camera and a laser, is used to check all of the steel/aluminum welds.
