- 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 r₁ = 3.75 cm to reach 1550 rpm. If the belt does not stretch or slip, calculate the angular acceleration a2 of the larger camshaft, which has a radius of r2 = 7.50 cm, during this time period. α₂ = rad/s²A flywheel with a diameter of 1.81 m is rotating at an angular speed of 197 rev/min.
