Torque and Rotational Motion Tutorial | Physics
Torque is a measure of how much a force acting on an object causes that object to rotate. The object rotates about an axis, which we will call the pivot point, and will label ' O '. We will call the force ' F '. The distance from the pivot point to the point where the force acts is called the moment arm, and is denoted by ' r '.

How do you calculate pulley torque? – forwardonclimate
How do you calculate pulley torque? To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r). If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm.
