3.12 The thin rod in Figure 3.43 always re- mains in contact with the leftmost cor- ner of the circular channel wherer = R = 0.75m. At the configuration shown in Figure 3.43 the absolute angular speed of the rod is 1.6rad/s in the counterclock- wise direction. Find the velocity of point A on the rod at this instant. (answer: the magnitude of the velocity is 2.4m/s.) R 2m Figure 3.43 gravity

A variable torque is applied to a rotating wheel at time t = 0 and causes the clockwise angular acceler- ation to increase linearly with the clockwise angular displacement 0 of the wheel during the next 30 revo- lutions. When the wheel has turned the additional 30 revolutions, its angular velocity is 90 rad/s. Deter- mine its angular velocity wo at the start of the inter- val at t = 0.
