The point at which the entire weight of the body
may be considered as concentrated.
A single vertical upward force equal to the weight
and applied at the center of gravity will keep the

Equilibrium
An object is in Equilibrium when:
1. There is no net force acting on the object
2. There is no net Torque (well get to this later)
In other words, the object is NOT

MOMENT
(TORQUE)
MOMENT/ TORQUE ()
-The ability of a force to rotate a body or system
about an axis.
-Mathematically, it is the product of the force and
its lever arm or moment arm.
