Question

Explain torque with an example.

Answer 1

Explanation of torque:

1. Torque is defined as the moment of force.
2. The rotational equivalent of force is called torque.
3. If $r$ is the radius of the rotational motion, and $F$ is the force applied, then torque is given as $\tau =rF\sin \theta$.
4. For example, when a force is applied to a door with hinges, it undergoes a rotational motion.
5. The vector product of the distance between the hinge and the door handle, and the force applied on the handle will give us the total torque acting on the door.
