QUESTION:

Consider the two rotating systems shown in Figure 11–37, each consisting of a mass m attached to a rod of negligible mass pivoted at one end. On the left, the mass is attached at the midpoint of the rod; to the right, it is attached to the free end of the rod. The rods are released from rest in the horizontal position at the same time. When the rod to the left reaches the vertical position, is the rod to the right not yet vertical (location A), vertical (location B), or past vertical (location C)? Explain.

ANSWER:

Solution 86GP

Step 1 of 2

In order to determine the position of the rod to the right, we are required to calculate the angular acceleration of each system.
