Determine the tension in the cable.
A uniform bar with a length of 5 meters and a mass of 25 kg is attached to a building by an axis at its left end. A box of mass 15 kg sits on the bar at a distance of 1.81 m from the left end. The right end of the bar is supported by a cable that is also attached to the building. The angle between the cable and the bar is 53 degrees.
Determine the tension in the cable.
