In Fig. 10-31, wheel A of radius rA = 10 cm is coupled by belt B to wheel C of radius rC = 25 cm. The angular speed of wheel A is increased from rest at a constant rate of 1.6 rad/s2. Find the time needed for wheel C to reach an angular speed of 100 rev/min, Assuming the belt does not slip. (If the belt does not slip, the linear speeds at the two rims must be equal.)
