The 3-kg slider P moves inside the frictionless horizontal tube. The hollow tube assembly rotates about a vertical axis at the rate w == 0.75t where 0 and t are expressed in rad/s and seconds, respectively. As the assembly rotates, the slider P moves outward from the vertical axis with a constant speed of 0.5 m/s. Knowing that at t = 0, r = 0, determine the time at which the tension T in the cord is equal to the magnitude of the horizontal force Fe exerted on the slider by the tube.

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 for a crankshaft with a radius of rı = 4.75 cm to reach 1350 rpm. If the belt does not stretch or slip, calculate the angular acceleration a2 of the larger camshaft, which has a radius of r2 = 9.50 cm, during this time period. a2 = rad/s?
