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.
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 best
