Problem
A 5.0 m long uniform beam of mass 20 kg is hinged to a wall at its left end and held horizontally by a cable attached to the right end of the beam. The cable makes an angle of 30∘ above the beam. Neglecting the mass of the cable, determine the tension required in the cable to maintain equilibrium. (Use g=9.8m/s2.)
