A uniform horizontal rod of length \(L\) supported by a hinge at \(P\) and an angled cable.
A uniform horizontal rod of length \(L\) supported by a hinge at \(P\) and an angled cable.
A uniform rod of length \(L\) and mass \(M\) is attached to a vertical wall by a frictionless hinge at point \(P\). The rod is maintained in static equilibrium in a horizontal orientation by a light cable. The cable is attached to the rod at a distance \(d = \dfrac{L}{3}\) from the hinge and connects to the wall at a point vertically above \(P\), making an acute angle \(\theta\) with the rod. Which of the following correctly pairs the direction of the vertical component with the direction of the horizontal component of the force exerted by the hinge on the rod at point \(P\)?
