A beam of mass 4 kg and length L= 1.3 m is propped by a hinge and a cable C (neglect the mass of the cable). The cable is tied to at its end and tied to the building above the beam, at the angle indicated in the diagram. Hanging from the bottom of the beam at 0.2 m from the right end is a shopping sign of mass 16 kg.
Calculate the magnitude of the tension |𝑇| in the cable C.
Calculate the force by the hinge on the beam.
