The uniform slender bar ABC weighs 5.2 lb and is
initially at rest with end A bearing against the stop in
the horizontal guide. When a constant couple M = 72.3
lb-in. is applied to end C, the bar rotates causing end
A to strike the side of the vertical guide with a velocity
of 10.9 ft/sec. Calculate the loss of energy ΔE (enter a
positive number) due to friction in the guides and rollers. The
mass of the rollers...
