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 = 53.13 degrees, the angular velocity of the gun tube is 10

rad/sec as shown. The turret is rotating about the vertical axis at a constant rate of 2 = 2 rad/sec.

Determine the angular acceleration of the gun tube, Ö, and the couple reaction exerted by the gun

tube on the pin at point A.
