The thin uniform bar AB of mass m and length L hangs from a wheel at A, which rolls freely on the horizontal bar DE. In the following problems, neglect the mass of the wheel and assume that the wheel never separates from the horizontal bar.

Figure P7.47

If the bar is released from rest at the angle θ, determine, immediately after release, the angular acceleration of the bar, the force on the bar at A, and the acceleration of end A.
