DisciplinesinMechanicalEng.

The engineer might start from a blank sheet of paper,

conceivesomething new, develop and refine it so that it

works reliably, and all the while satisfy constraints of

manufacturability,safety,andcost.

An engineer creates a machine, product, or system that

helps someone to solve a technical problem

Mechanical engineers develop hardware that exploits

those elements in order to serve a useful purpose.

Original design is always the underlying factor:
