Question

The axle radius is 1 m and the wheel radius is 4 m. A 1600-N load is attached to the axle via a cable. A worker supports the load by holding on to the cable attached to the wheel. The moment of inertia of the wheel/axle system is 5 kg•m2.

a) How much force must be applied to the wheel to maintain static or dynamic equilibrium?

b) If the load is lifted 10 m, what is its change in potential energy?

c) Assuming the load was lifted in dynamical equilibrium, what work did the worker do?

d) How much cable does the worker use to lift the load 10 m?
