here are the conditions of produce torque:Let's take a particular example of a disk rotating around an axis through its centre:



If the component of the torque parallel to the axis is TaTa then the disk will start to rotate according to the angular version of Newton's second law:

Ta=Iω˙(1)(1)Ta=Iω˙

where ω˙ω˙ is the angular acceleration and IIis the moment of inertia. The obvious way to make this rotate is to apply a tangential force:



In this case the magnitude of the torque is just T=rFT=rF and the direction of the torque vector is parallel to the axis so Ta=T=rFTa=T=rF and equation (1) tells us that the disk will start rotating.
