Two wheels, each of mass m = 100 g and radius R = 2 cm, are connected by a bar of length l = 10 cm, and recline against a horizonal and a vertical surface, respectively. A torque T = 34 mN?m acts on wheel A to keep the car propped in the equilibrium configuration shown. Assuming rough contact between the wheels and surfaces and neglecting the mass of the bar:

(a) draw the free body diagram of each wheel,

(b) write down the equations of equilibrium for each wheel.

(You do not need to solve the equations for the unknowns.)
