										Dear Baba
The measure of a force's tendency to produce a rotation about an axis is called torque. That 	is, if a force is used to begin to spin something, or to attempt to spin something, a torque is generated. A torque 	would also be generated if a force was used to stop something from spinning.

$\boldsymbol \tau = \mathbf{r}\times \mathbf{F}\,\!$ $\tau = rF\sin \theta\,\!$
where
τ is the torque vector and τ is the magnitude of the torque,r is the displacement vector (a vector from the point from which torque is measured to the point where force is applied), and r is the length (or magnitude) of the lever arm vector,F is the force vector, and F is the magnitude of the force,× denotes the cross product,θ is the angle between the force vector and the lever arm vector.All the bestAKASH GOYALPlease feel free to post as many doubts on our discussion forum as you can.
