The spring is uncompressed when the uniform sender bar AB is in the vertical position shown. Bar AB with a mass of 50 kg and a length of 1 m is released from rest in the position where the bar has been rotated 30° clockwise from the position shown. This initial position of the bar AB is illustrated using the dashed line in the figure. Neglect any sag of the spring as well as the spring mass. (b) Find the angular velocity of the bar when it reaches the vertical position.

2. Consider the 5-1lb bar with length of 2½ feet and width of 2 inches. Small frictionless bearings are mounted to the ends, constraining the motion of the bar to the horizontal x and y slots. The bar starts at rest at positioned at 0= 45°. If an angular acceleration of 3 rad/s² is desired, what moment M must be applied to the bar? What are the reaction forces at A and B at that instant? Additional question: Does the width of the bar matter, or is it appropriate to consider the bar as a slender rod? Consider errors of less than 2% negligible.
The figure shows the cross section of a uniform 239-lb ventilator door hinged about its upper horizontal edge at O. The door is controlled by the spring-loaded cable which passes over the small pulley at A. The spring has a stiffness of 16.6 lb per foot of stretch and is undeformed when 8-0. If the door is released from rest in the horizontal position, determine the maximum angular velocity reached by the door and the corresponding angle 0. Answer: @max 4.2¹ rad/sec at 8-i
