A governor (centrifugal pendulum) consists of two 200–g spheres attached by light, rigid 10.0–cm rods to a vertical rotating axle. The rods are hinged so that the spheres swing out from the axle as they rotate with it. However, when the angle θ is 45.0°, the spheres encounter the wall of the cylinder in which the governor is rotating (see the figure above). (a) What is the minimum rate of rotation, in revolutions per minute, required for the spheres to touch the wall? (b) If the coefficient of kinetic friction between the spheres and the wall is 0.35, how much retarding force results as the spheres rub against the wall when the mechanism is rotating at 300 rev⁄min?
