Equilibrium
A body being acted upon by a system of forces is said to be in equilibrium if the body does not have tendency to rotate or to slide.
#If any body in equilibrium, the resultant force R=0. And its component also zero.
Fx =0
Fy =0

Free Body Diagram
A free body is a representation of an object, mainly a rigid body, which shows all the forces acting on it.

Flexible Cords
Cables are structural elements that are assumed to be inextensible but flexible.

Friction

Friction
Friction is a resistance force.
There are two kinds of friction. Such as……
1.Static friction.
2.Kinetic friction.
A surface which offers frictional resistance is said to be rough surface. And a frictionless surface is said to be smooth surface.
