8. 2) Rods AB and BC are linked at Band have weights of 18 lb and 37 lb,
respectively. The 8-lb collar C, which is connected to BC and the spring, slides freely
along the smooth vertical guide. The lengths of the rods are 4 = 1.4 ft and 2 = 2.9 ft.
If the system is released from rest when 0 = 0°, determine the magnitude of the
angular velocity (in rad/s) of rod BC when 0 = 90°. The attached spring has spring
constant k = 20 Ib/ft, and is unstretched when 0 = 0°. Please pay attention: the
numbers may change since they are randomized. Your answer must include 2 places
after the decimal point. Take g= 32.2 ft/s2.
