Two forces are applied to a merry-go-round at an outer radius of 3.8 m and an inner radius of 1.6 m as shown in the diagram. The force on the outside is 56 N, while the force on the inside is 20 N. (a) What is the torque about the outer radius due to the 56 N force? (b) What is the torque about the inner radius due to the 20 N force? (c) What is the net torque acting on the merry-go-round? Assume counterclockwise is negative and clockwise is positive.
