To understand <strong>to</strong>rque you need <strong>to</strong> know the words we use<strong>to</strong> describe circles.•The circumference is outside of the circle.•The radius is a straight line from the centre <strong>to</strong> thecircumference.•A tangent is a straight line that <strong>to</strong>uches the circumference.•The angle between a tangent and the radius is always 90degrees.The force acts in a straight lineWe always think of the force acting in a straight line andat the outside of the circular pathway.The angle between the force and the radius is always 90degrees.The <strong>to</strong>rque or turning force is equal <strong>to</strong> the size of theforce and the radius of the rotation. Simple mathematicsis <strong>used</strong> <strong>to</strong> find the <strong>to</strong>rque.Torque = Force x radius of rotation (distance)This explains why you should hold the end of thespanner rather than somewhere near the centre.36
