**1 Principle of Super
Position:**

Sometimes the number of external forces
and inertial forces acting on a mechanism are too much for graphical solution.
In this case we apply the method of superposition. Using superposition the
entire system is broken up into (n) problems, where n is the number of forces,
by considering the external and inertial forces of each link individually.
Response of a linear system to several forces acting simultaneously is equal to
the sum of responses of the system to the forces individually. This approach is
useful because it can be performed by graphically.

**2 Free Body Diagram:**

A free body diagram is a pictorial
representation often used by physicists and engineers to analyze the forces
acting on a body of interest. A free body diagram shows all forces of all types
acting on this body. Drawing such a diagram can aid in solving for the unknown
forces or the equations of motion of the body. Creating a free body diagram can
make it easier to understand the forces, and torques or moments, in relation to
one another and suggest the proper concepts to apply in order to find the
solution to a problem. The diagrams are also used as a conceptual device to help
identify the internal forcesâ€”for example, shear forces and bending moments in
beamsâ€”which are developed within structures.
