Mechanical engineers focus on how things work and see the world as parts in motion—they research, design and develop a variety of products ranging from engines, turbines, and generators; to refrigeration and air-conditioning systems; to medical devices; to elevators and escalators.
Mechanical engineers will research the feasibility, design, operation and performance of mechanisms, components and systems. They plan and manage projects; prepare material, cost and timing estimates; and design specifications for machinery and systems. They supervise and inspect the installation, modification and commissioning of mechanical systems at construction sites or in industrial facilities and they will develop maintenance standards, schedules and programs to provide guidance to industrial maintenance crews. Mechanical engineers will investigate mechanical failures or unexpected maintenance problems and determine solutions.
