Question

Explain the turning effect of force and state the factors affecting it ??

Answer 1

Dear Student

The moment of force or the torque due to a force gives us the turning effect of force about the fixed point or axis.It is measured by the product of magnitude of force and perpendicular distance of the line of action of force from the axis of rotation. For eg: when we switch on a fan , the centre of fan remains unmoved , while the fan rotates with angular acceleration. As the centre of mass of the fan remains at rest, the vector sum of external forces acting on the fan must be zero. However, we cannot produce angular acceleration without applying external force . This angular acceleration is produced by moment of force or torque due to force.

Factors affecting turning effect of force are displacement and movement.
