Mechanical engineering is an engineering branch that combines engineering

physics and mathematics principles with materials science to design, analyse, 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.

Today mechanical engineers are pursuing developments in such areas as composites, mechatronics, and nanotechnology. It also overlaps with aerospace engineering, metallurgical engineering, civil engineering, electrical engineering, manufacturing engineering, chemical engineering, industrial engineering, and other engineering disciplines to varying amounts.

In this section, we will deal with certain important questions pertaining to basic mechanical engineering as such

• What is torque?

• What is latent heat?

• What is limiting friction ?

• What are manometers ? etc.
