Question

The frame of mass $m = 4.2$ kg is welded together from uniform slender rods of length $L =695$ mm. The frame is released from rest in the upper position shown and constrained to fall vertically by two light rollers which travel along the smooth slots. The roller at A catches in the support at O without rebounding and serves as a hinge for the frame as it rotates thereafter. Determine the angular velocity of the frame an instant after the roller at A engages the support at O. L A L B

Step 1

2$ kg Length of each slender rod, $L = 695$ mm $= 0.695$ m The frame is released from rest, so its initial velocity is 0. The frame falls vertically until roller A reaches support O. At O, roller A acts as a hinge, and the frame rotates. We need to find the Show more…
