To solve this problem, it is necessary to apply the concepts related to force described in Newton's second law, so that
F = ma
Where,
m = mass
a = Acceleration (Gravitational acceleration when there is action over the object of the earth)
Torque, as we know, is the force applied at a certain distance, that is,
Where
F= Force
d = Distance
Our values are given as,
Since the system is in equilibrium the difference of the torques is the result of the total Torque applied, that is to say
Therefore the magnitude of the frictional torque at the axle of the pulley if the system remains at rest when the balls are released is
