The 10-kg uniform slender rod is suspended at rest when the force of F = 150 N is applied to its end. Determine the angular velocity of the rod when it has rotated 180° clockwise from the position shown. The force is always perpendicular to the rod.
The disk has a weight of 10 lb and is pinned at its center O.
If a vertical force of P = 2 lb is applied to the cord wrapped
around its outer rim, determine the angular velocity af the
disk in four scconds starting from rest. Neglect the mass of
the cord.
The torsional spring is untwisted when the slender uniform rod is in the vertical position. The rod has a length of 0.81 m
and a mass of 4.7 kg. The rod is released from rest in the horizontal position shown. What should the stiffness Kof the
spring be so that the rod will have an angular speed of o = 4 rad/s when it passes the vertical position? The rod rotates
freely about the fixed pin support at O. The motion occurs in a vertical plane. Choose the correct answer.
