The radial component of the force has no contribution to the torque because it passes through the pivot point. So, it is only the tangential component of the force which affects torque (since it is perpendicular to the line between the point of action of the force and the pivot point).

What type of force is torque?

In physics and mechanics, torque is the rotational equivalent of linear force. It is also referred to as the moment, moment of force, rotational force or turning effect, depending on the field of study.

What type of motion is torque?

In this article, we answer the common question “what is torque?” Although torque refers to rotational motion, it is a fundamental concept in linear motion applications.
