Mechanics being a branch of physical science which deals with the motion of bodies under the action of forces. in other words, it determines the state of motion of bodies under the effect of forces or conversely it determines the forces imparting a certain state of motion to bodies. mechanics, therefore forms the basis for understanding the behavior as well as the design and analysis of all engineering structures and machines hence the study of mechanics is of vital importance for all those engaged in the engineering profession. Thus it gives us ideas about ;
- The movement of bodies
- The forces acting on bodies
- The effect of the forces on the bodies upon which they act.
