M -L- Support Cable M 32. The figure above shows a uniform beam of length L and mass M that hangs horizontally and is attached to a vertical wall. A block of mass M is suspended from the far end of the beam by a cable. A support cable runs from the wall to the outer edge of the beam. Both cables are of negligible mass. The wall exerts a force Fw on the left end of the beam. For which of the following actions is the magnitude of the vertical component of Fw LARGEST? (A) Keeping the support cable and block as shown in the diagram (B) Moving the lower end of the support cable to the center of the beam and leaving the block at the outer end of the beam (C) Keeping the lower end of the support cable at the outer end of the beam and moving the block to the center of the beam (D) Moving both the support cable and the block to the center of the beam M -L- Support Cable M 32.
