Problem 5. (20 points)A 5000 lb tank gun tube is modeled below connected to the turret by a pin connection that allows rotation about the pin axis. When 0 =

53.13 degrees, the angular velocity of the gun tube is 10rad/sec as shown. The turret is rotating about the vertical axis at a constant rate of = 2 rad/sec.Determine the angular acceleration of the gun tube, 0, and the couple reaction exerted by the gun tube on the pin at point A.
