a horizontal rod, see figure below, is 10m long. the rod weights 500.0n and with a center of mass located at c, is 3.00m from point a in the figure below. at point a, a force of 1000.0n acts downward. at point b, a force of 750n acts downward. at point d, 2.00m from point b, a force of 400.0n acts upward. at point e, 1.00m from point a, a force of 750.0n acts upward. what is the magnitude and direction of the force that must be employed to establish translational equilibrium?
