I need expert help to solve the following question:

Question: A string that passes over a pulley has a 0.377-kg mass attached to one end and a 0.610-kg mass attached to the other end. The pulley, which is a disk of radius 9.40 cm, has friction in its axle.

Question 1: What is the magnitude of the frictional torque that must be exerted by the axle if the system is to be in static equilibrium?
