Mechanical engineering is an engineering branch that 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 branches.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, watercraft, robotics, medical devices, weapons, and others.

Typical responsibilities of a manufacturing engineer include designing new equipment, processes,
procedures and systems
purchasing and installing equipment, repairing equipment, responding to breakdowns,
investigating production problems, planning and organising maintenance liaising with suppliers,
customers and research and development staff.
17
Nuclear engineers research and develop the processes, instruments, and systems used to benefit from nuclear energy and radiation. Design or develop nuclear equipment, such as reactor cores, radiation shielding, and associated instrumentation. Direct operating or maintenance activities of operational nuclear power plants to ensure that they meet safety standards. Write operational instructions to be used in nuclear plant operation or in handling and disposing of nuclear waste.
18
