A uniform beam supported by a hinge and a vertical cable.
A uniform beam supported by a hinge and a vertical cable.
A uniform horizontal beam of mass \(M\) and length \(L\) is attached to a vertical wall by a hinge. A vertical cable is initially attached to the right end of the beam to maintain it in a horizontal position. The cable is then moved from the right end to the center of the beam (the location of the center of mass). Which of the following correctly describes how the tension in the cable and the magnitude of the vertical force exerted by the hinge on the beam change?

(A) IncreasesIncreases
(B) IncreasesDecreases
(C) DecreasesIncreases
(D) DecreasesDecreases
