A 30⁰ 1 m D 3 m Figure 2 B A beam AB, of mass 20 kg and length 3 m, is smoothly hinged to a vertical wall at one end A. The beam is held in equilibrium in a horizontal position by a rope of length 1 m. One end of the rope is fixed to a point C' on the wall which is vertically above A. The other end of the rope is fixed to the point D on the beam so that angle ACD is 30°, as shown in Figure 2. The beam is modelled as a uniform rod and the rope is modelled as a light inextensible string. Using the model, find the tension in the rope.
