The principle of transmissibility of forces states that, when a force acts upon a body, its effect is minimum, if it acts at the centre of gravity of the body.

A smooth cylinder lying on a horizontal surface is in neutral equilibrium
A couple produces rotational motion.
The algebraic sum of the forces, constituting the couple is zero.
The algebraic sum of the forces, constituting the couple, about any point is the same.
A couple cannon be balanced by a single force but can be balanced only by a couple of opposite sense.
The point, through which the whole weight of the body acts, irrespective of its position, is known as centre of gravity.
