Question

calculate force required to keep the body in equilibrium​

Answer 1

A N S W E R :

Equilibrium of an object is achieved when the sum of forces equals zero. Since forces have both magnitude and direction, this means the sum of the forces in each direction (x plane, y plane and z plane) must be zero.

A special case of equilibrium exists when there are no forces on the object, since this satisfies the condition of sum of forces equals zero.

If there is one force present, the object cannot be in equilibrium. The object will change velocity in the direction of the force.

To achieve equilibrium when one force is already present a minimum of one additional force is required in the opposite direction. Or, several forces that effectively are equal and opposite to the one force will also achieve equilibrium.
