Mechanical engineering Mechanical engineering is the study of physical machines that may involve force and movement. It is an engineering branch that combines engineering physics and mathematics principles with materials science, to design, analyze, manufacture, and maintain mechanical systems.[1] It is one of the oldest and broadest of the engineering branches. Mechanical Engineering is a branch of engineering that deals with the design, development, production, and maintenance of mechanical systems. This can encompass a wide range of industries, including aerospace, automotive, energy, robotics, and more. Mechanical engineers are responsible for designing, testing, and manufacturing a variety of products, including machines, tools, engines, and other mechanical systems. They must have a strong understanding of materials science, thermodynamics, and structural analysis to create safe, efficient, and funct...
