The 17.9 cm diameter disk rotates on an axle through its center. F1=22.1 N, F2=32.4 N, F3=32.4 N, F4=22.1 N, and d=4.74 cm. What is the net torque about the axle?

From the description, one cannot assertain what the forces are, where they act, and in what directions.

Net torque=sum of crossproduct of force, distance.
