mecahnical engineers
Mechanical engineering, one of the oldest and broadest engineering disciplines, combines engineering physics and mathematics principles with materials science to design , analyze, manufacture and maintain mechanical systems . It is one of the oldest and broadest of the engineering disciplines . The mechanical engineering field requires an understanding of core areas including mechanics , dynamics , thermodynamics , materials science , structural analysis , and electricity . In addition to these core principles, mechanical engineers use tools such as computer-aided design (CAD), computer-aided manufacturing (CAM), and product lifecycle management to design and analyze manufacturing plants , industrial equipment and machinery , heating and cooling systems , transport systems, aircraft , watercra...
