Introduction to Statics
Engineering Mechanics is the physical science concerned with behaviour of a body when the body is at rest or in motion. The bodies are acted on by mechanical disturbances. Mechanics are divided into two categories-Statics and Dynamics. The study which restricts the body at rest only, is called statics. The study which deals with the body in motion is called Dynamics. Dynamics is further divided into two categories-Kinematics and Kinetics. The study of a body in motion without considering forces is called Kinematics and the study of a body in motion considering the forces is called Kinetics. The classification of Mechanics is given in block diagram in Figure 1.1.
