An Introduction to Mechanics

Mechanics is a branch of physical science that deals with the study of the state of an object at rest or in motion under the action of forces.

t is generally classified as rigid body mechanics, deformable body mechanics, and fluid mechanics.

Rigid body mechanics study those objects in which deformation is negligible under the action of forces.

It can be branched into statics and dynamics. Statics deal with the state of the objects being at rest, whereas dynamics deals with the objects in motion.

Dynamics is further divided into kinematics and kinetics, where the forces responsible for the motion are neglected and considered, respectively.

Deformable body mechanics studies the deformation of an object under the action of forces.

The study of motion and forces of fluids is termed fluid mechanics. It is further classified into compressible and incompressible fluids.

Designing and analyzing of structures such as buildings, leaf springs in automobiles, crane hooks, pneumatic nail guns, hydraulic braking systems, and industrial robots are based on the principles of mechanics.
