Question

Most gasoline engines in today's automobiles are belt driven. This means that the crankshaft, a rod which rotates and drives the pistons, is timed to the camshaft, the mechanism which actuates the valves, by means of a belt. Starting from rest, assume it takes t 0.0100 s for a crankshaft with a radius of η = 4.25 cm to reach 1350 rpm. If the belt doesn't stretch or slip, calculate the angular acceleration, α2, of the larger camshaft, which has a radius of r2 = 8.50 cm, during this time period. Number rad/s2
