The American Engineers Council for Professional Development (ECPD, the predecessor of ABET has defined "engineering" as:| Scientists report the world every bit it is; engineers create the world that has never been. |
"Engineering is quite dissimilar from science. Scientists attempt to empathise nature. Engineers attempt to brand things that do non be inwards nature. Engineers stress invention. To embody an excogitation the engineer must pose his persuasion inwards concrete price together with blueprint something that people tin lav use. That something tin lav live a device, a gadget, a material, a method, a computing program, an innovative experiment, a novel solution to a problem, or an improvement on what is existing. Since a blueprint has to live concrete, it must have got its geometry, dimensions, together with characteristic numbers. Almost all engineers working on novel designs notice that they do non have got all the needed information. Most often, they are limited past times insufficient scientific knowledge. Thus they report mathematics, physics, chemistry, biological scientific discipline together with mechanics. Often they have got to add together to the sciences relevant to their profession. Thus engineering scientific discipline sciences are born." [1]

5) Robotics
... together with the listing continues, but these are the major areas where the futurity of mechanical engineering scientific discipline volition logically live applied. Now let’s empathise of what they are together with regard how they are the future.
Nano-engineering
“Nano” is the give-and-take used to mensurate whatsoever object that is measured inwards scales of 10 to the mightiness of -9. They are microscopic together with only electron microscopes are used to regard such objects. Creating anything of that microscopic size inwards itself is a stellar task, allow lone applying the principles of mechanical engineering scientific discipline at that level. Nano-engineering is mainly used inwards the champaign of enquiry together with medicine. It is used to create materials that are non affected past times normal factors similar weather condition together with corrosion, etc. Materials designed past times nano-engineering are lighter together with stronger than other materials. The mechanical construction of the materials is changed thereby giving enhanced properties to the materials. H5N1 concept using carbon nanotubes past times NASA is said to live able to link the surface of the reason together with the satellite thereby making a straight connective to a satellite. This is the potential of nano-engineering.
Biomechanics
Bionics is the boon of modern medical scientific discipline that promises to brand the lives of millions better. “Bionic” is the term used to refer to the artificial stuff or object that mimics the activity done past times a portion of the human body. For example, a bionic arm mimics the actions of a human arm; the bionic leg mimics the human leg. They are created using the principles of biomechanics. Experiments are going on that hope bionic chests together with bionic necks. The functions together with the operations of the bionics that re-create their human counterparts heavily depend on the principles set past times mechanical engineering. Bionics is 1 expanse where nosotros tin lav regard the wonders of what the futurity of mechanical engineering scientific discipline has inwards concur for us together with how it is existence applied inwards day-to-day life.
Automobiles together with Aviation
Mechanical Engineering has helped inwards creating the fastest cars that are capable of traveling 400+ kph (248 mph) together with inwards the making of the most comfortable vehicles on the planet that are used past times millions. The huge aircraft that enable millions every 24-hour interval to hit from 1 corner of the globe to the other inwards a affair of hours all are the final result of extensive improvement together with implementation of mechanical engineering.
