**Introduction of Engineering Mechanics:-**

* The Engineering Mechanics* is that branch of Engineering-science which deals with the principles of mechanics along with their applications to engineering problems. It is sub-divided into the following two main groups:

**(a) Statics, and (b) Dynamics**

__The Statics__ is that branch of Engineering Mechanics which deals with the forces and their effects, while acting upon the bodies at rest.

__The Dynamics __is that branch of Engineering Mechanics which deals with the forces and their effects, while acting upon the bodies in motion. It is further sub-divided into the following two branches:

*(i) Kinetics, and (ii) Kinematics*

__The Kinetics __is that branch of Dynamics, which deals with the bodies in motion due to the application of forces.

__The Kinematics__ is that branch of Dynamics which deals with the bodies in motion without taking into account the forces which are responsible for the motion.
