What are the relationship between Electronics engineering and Mechanical engineering?

More than ever, and getting more and more as time goes on, they are becoming inseparable. Look at the simple example of an automotive engineer carburetor. At one time, a typical carburetor was comprised of seven systems all working together to optimize the performance of an internal-combustion engine at a wide range of RPM, horsepower output, temperature, fuel composition, load, etc., etc.. And those systems were entirely mechanical. Each one a dizzying Rube Goldberg contraption refined to a fascinating efficiency, working together to keep explosions inside an iron block turning a crank to move a car more efficiently. Today, carburetors are rare, and have been replaced by fuel injection. And the mechanical contrivances have been replaced by computers who have been programmed with the ideal performance curve that we used to rely on those mechanical things to approximate. Computers simply have a map of what we want the machine to do, and they control various effectors (mechanical output devices like relays and injectors and valves and such) by using data from sensors to see what the current state is and how to keep it matching our expectations.

In short, mechanical engineering is replacing more and more purely mechanical systems with hybrid mechanical and electronic systems. Without a bunch of data, you simply can't look at most machines today and figure out what they do. You have to get to the electronic / data level, which is usually invisible to us humans. So we rely on other devices to peer into those tiny, electronic machines.

So the relationship between mechanical and electronic engineering today is essentially a permanent marriage.

Hello Partap, the relationships between Electronics Engineering and Mechanical engineering are quite diverse, they are two complimentary Engineering trades.

For example, within Electricity generation, a rotating machine (generator drive unit, water or wind turbine or gas pressure turbine) spins another rotating machine, an alternator, to generate electricity using the principles of magnetic flux crossing inductive magnetically coupled coils of wire,( this induces an EMF -Electromotive Force) with alternating cyclic transmittance/flow ,the mechanical forces translated into rotation about a moment are transferred (with inefficiencies ) into Electrical energy, which can then be transmitted, converted and/or stored for use by rectification and power management circuitry..

When an Aircraft stabiliser or wing flap moves, under the lever action of a hydraulic system (powered by an Electrically driven motorised pump or by gearbox driven direct drive pump taking power from the aircraft engine) there are rotary shaft encoders which are sensors outputting a digital signal which is interpreted by the software on various system computers as an angular position (an angle) or a rate of transit or rotation, giving the angle of the wing flap or the stabiliser or elevator on the aircraft tail, linear encoders and hall effect sensors also provide control signals ..

This is a direct system feedback interaction between a mechanical system and an electronic system and uses sensors to allow the pilot to see accurate information on displays in the flight cockpit as well as allowing the autopilot to function, the Electronic control interface allows "fly by wire" Electronic control of the aircraft engines and control surfaces, this is a good example of where the two disciplines work together..

Mechanical Engineering deals with designing a component, machine, system or process by using principles of motion, energy and force. You will focus on creating new technology that meets human needs: the engine of a car, the printer that helps you copy a document, or the air-conditioning that cools you during hot summer days.

As a mechanical engineer you can also go into research in areas like nanotechnology, development of composite materials, biomedical applications, or environmental conservation.

Mechatronics combines principles of mechanics, electronics and computing to improve technical systems and to create new equipment with built-in 'artificial intelligence'. The autofocus camera, automated guided vehicles, robots and anti-lock braking systems .
