This time, the swing bar of mass mbar is pivoted at a different point, as shown in the figure. (Figure 3) Find the magnitude of the angular acceleration α of the swing bar. Be sure to use the absolute value function in your answer, since no comparison of m1, m2, and mbar has been made. Express your answer in terms of some or all of the quantities m1, m2, mbar, l, as well as the acceleration due to gravity g. Enter the absolute value function as abs(). For instance, enter abs(x*y) for |xy|.
