In the simplified sketch of a ball bearing shown, the diameter of the inner race (cylinder) \( A \) is \( 60 \mathrm{~mm} \) and the diameter of each ball is \( 10 \mathrm{~mm} \). The outer race \( B \) is stationary while the inner race has an angular speed of \( 3200 \mathrm{rpm} \). Determine (a) the speed of the centre of each ball, (b) the angular speed of each ball, and (c) the number of times per minute each ball describes a complete circle. Ignore the thickness of the races. Diagram From [1]
