Importance of Mechanics

Mechanics is considered as the branch of science which deals with the state of rest or motion of bodies subjected to the action of forces.. It is further divided into three branches; rigid body mechanics, deformable-body mechanics and fluid mechanics. Rigid-body mechanics consists of two parts; statics and dynamics. Statics is concerned with equilibrium of bodies at rest or moving with constant velocity. Dynamics deals with bodies moving with acceleration. Most of the civil engineering structures are designed to be in equibrium which needs application of the principles of statics.
