Problem
A light horizontal beam of length 2.0m is hinged to a vertical wall at its left end. At the beam’s right end, a 400N crate hangs from a rope that makes an angle of 30∘ above the beam. The tension in the rope is 500N. Neglect the beam’s own weight. Which set of equilibrium conditions is satisfied for the beam?
(a) Both translational and rotational equilibrium
(b) Neither translational nor rotational equilibrium
(c) Translational equilibrium only
(d) Rotational equilibrium only
