Equilibrium Problem: Bar Supported by Cable

This is an adjustable equilibrium problem involving a uniform bar with a mass on it. The bar has an axis at its left end and is supported at its right end by a cable. The mass of the bar and box, the length of the bar, the position of the box and the angle of the cable can all be adjusted. Use the given quantities to determine the tension in the cable. Check your free body diagram, equations, and your determined tension.
