A traffic light hangs from a 7.2-m long beam (AB) that is attached to a pole by a hinge (A), as shown. A horizontal (massless) cable (CD) supports the beam, making a 37° angle. The cable is attached to the pole 3.8 m above the hinge. The mass of the beam is 12 kg, and the mass of the traffic light is 22 kg. What is the tension in the cable? Also, the hinge exerts a force— with both horizontal and vertical components— on the beam. Find the magnitude of this force.

Center of Gravity of a system

The centre of gravity is a property that is based on the geometry of a rigid body or any particle. It is described as an equilibrium point or a hypothetical location where the total weight of the body is concentrated.
