Most gasoline engines in today's automobiles are belt driven. This means that the crankshaft, a rod which rotates and drives thepistons, is timed to the camshaft, the mechanism which actuates the valves, by means of a belt.
Starting from rest, assume it takes t = 0.0540 s for a crankshaft with a radius of r1 = 3.25 cm to reach 1450 rpm. If the belt does not stretch or slip, calculate the angular acceleration a(2) of the larger camshaft, which has a radius of r2 = 5.50 cm, during this time period.
