A uniform horizontal beam supported by a wall hinge and a diagonal wire.
A uniform horizontal beam supported by a wall hinge and a diagonal wire.
A uniform horizontal beam of mass \(M\) and length \(L\) is attached to a vertical wall by a frictionless hinge at its left end. A light wire connects the right end of the beam to an anchor on the wall at a height \(h\) directly above the hinge, maintaining the beam in static equilibrium. The wire is then adjusted so that its anchor on the wall is moved downward to a new position closer to the hinge, reducing \(h\) while the beam remains horizontal. How do the magnitudes of the horizontal component \(F_x\) and the vertical component \(F_y\) of the force exerted by the hinge on the beam change as a result of moving the anchor downward?
