A. Find each of the three moments (M₁, M2, M3) due to the applied forces - use ccw as positive.

B. Find the resultant moment, which is the sum of the individual moments (EM). Note that, in

this case, the system may not be in rotational equilibrium. Label your resultant moment as

positive or negative and write clockwise or counterclockwise by this label, corresponding to

which direction the resulting rotation would be.
