Think about what you did today. Every one of these activities was influenced by a mechanical engineer.
Mechanical engineers are concerned with the principles of motion, energy and force.
Generally, a machine converts one form of movement into another. It is the responsibility of engineers to design machines whose parts and assemblies function in a safe and reliable, efficient and predictable fashion. In the words of one author, the mechanical engineer applies scientific method to the solution of mechanical problems. Indeed, the numerous laws and principles developed by scientists are the everyday tools of the mechanical engineer. Anything the engineer does that is related to the motion and dynamics of heat, gas, air, fluids and solid materials requires the understanding and application of science.
