Extracted text: The uniform slender bar ABC weighs 5.6 lb and is initially at rest with end A bearing against the stop in the horizontal guide. When a constant couple M = 77.7 lb-in. is applied to end C, the bar rotates causing end A to strike the side of the vertical guide witha velocity of 10.5 ft/sec. Calculate the loss of energy AE (enter a positive number) due to friction in the guides and rollers. The mass of the rollers may be neglected. M 9.3" B 9.3", 45° Answer: AE = i ft-lb
