Homework 9.A


As you will see in your analysis, if the distance d is too large in comparison with the length of the bar L, the bar cannot come to rest in equilibrium.

Shown below is the what is seen when the bar is released from its equilibrium state for d < L/2.

Shown below is an animation of the bar when it is released from rest for d > L/2. In this case, the block "bottoms out" on the horizontal support with d being too large for equilibrium. What in your analysis tells you the maximum value of d in order for the bar to be in equilibrium?
