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 = 0.0760 s t=0.0760 s for a crankshaft with a radius of r 1 = 4.75 cm r1=4.75 cm to reach 1850 rpm . 1850 rpm. if the belt does not stretch or slip, calculate the angular acceleration α 2 α2 of the larger camshaft, which has a radius of r 2 = 9.50 cm , r2=9.50 cm, during this time period.
