A string that passes over a pulley has a 0.330-kg mass attached toone end and a 0.641-kg mass attached to the other end. The pulley,which is a disk of radius 9.93 cm, has friction in its axle. Whatis the magnitude of the frictional torque that must be exerted bythe axle if the system is to be in static equilibrium?

I need help on how to solve this. It's very confusing for me.
