What Is The Torque On The Object?

When a force is applied on a body in such a way that rotation is produced in it, then rotational effect of the body is known as torque. Torque is the cross product of moment arm and force. Moment arm is the distance between rotational axis and force. Torque is a vector quantity and its direction is perpendicular to the plane containing force and moment arm. The unit of torque is joule.

Torque = moment arm x force

T = r x F

T = rF Sin(theta)

Theta is the angle between force and moment arm. The unit of torque can be defined as;

Unit of torque = unit moment arm * unit of force

Unit of torque = meter * newton

Unit of torque = joule
