Chapter 17.4, Problem 63P
The 10-lb bar is pinned at its center O and connected to a torsional spring. The spring has a stiffness k = 5 lb · ft/rad, so that the torque developed is M = (5θ) lb · ft, where θ is in radians. If the bar is released from rest when it is vertical at θ = 90°, determine its angular velocity at the instant θ = 45°.

If the cord is subjected to a horizontal force of P = 150 N, and gear is supported by a fixed pin at O,determine the angular velocity of the gear and the velocity of the 20-kg gear rack in 4 s, starting from rest. The mass of the gear is 50 kg and it has a radius of gyration of k0 = 125 mm. Assume that the contact surface between the gear rack and the horizontal plane is smooth.
In the figure, rod AB has a mass of 10 kg, and must slide within the slots as shown. If the spring is unstretched when θ = 0°, determine the angular velocity of the bar when it reaches that angle after being released from θ = 30°.
