Mechanical engineering is a branch of science that applies physical sciences and life sciences together with applied mathematics and economics to produce, transform, and all transport, properly use chemicals, materials & energy.
Advancements in computer science found applications designing & managing plants, simplifying calculations & drawings that previously had to be done manually. The completion of the Human Genome Project is also seen as
a major development.
Mechanical engineers use these core principles along with tools like computer-aided design, product lifecycle management to design and analyze manufacturing plants, industrial equipment and machinery, heating and cooling systems, transport systems, aircraft, robotics and medical devices.
