The motor A accelerates uniformly from zero to 3800 rev/min in 19 seconds after it is turned on at time t = 0. It drives a fan (not shown) which is attached to drum B. The effective pulley radii are shown in the figure. Determine (a) the number of revolutions turned by drum B during the 19-second startup period, (b) the angular velocity of drum B at time t = 8 s, and (c) the number of revolutions turned by drum B during the first 8 seconds of motion. Assume no belt slippage. Answers T= 60 mm = 150 mm A
