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. Typically, a safety factor is used so that the ...Web
