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?

Show all work, use additional paper if necessary.
