Turning effect is produced by                          

A)  tangential component of force

B)  radial component of force

C)  transverse component of force

D)  None of the above                                   

Correct Answer: C

Solution :

When an external force acting on a body has a tendency to rotate the body about an axis, then the force is said to exert a torque about the body about that axis. The torque is equal to product  of transverse component of  force and perpendicular distance from the axis of rotation. \[\tau =F\times r\]
