Answer
Two equal and opposite parallel forces, not acting along the same line form a couple.
A couple is always needed to produced a rotation.
Two examples in our daily life where we use couple are:
- Turning a water tap.
- Tightening the cap of a bottle.

A body is acted upon by two forces each of magnitude F, but in opposite directions. State the effect of the forces if
(a) both forces act at the same point of the body.
(b) the two forces act at two different points of the body at a separation r.
Draw a neat labelled diagram to show the direction of two forces acting on a body to produce rotation in it. Also mark the point O about which the rotation takes place.
Prove that
Moment of couple = Force x Couple arm.
Describe a simple experiment to verify the principle of moments, if you are supplied with a metre rule, a fulcrum and two springs with slotted weights.
