A 3m long cantilever with a mass of 250 kg is attached to a wall and also held in place with a steel cable that is attached to the far end of the cantilever at an angle of 30o with respect to the cantilever. A 5 kg mass too hangs from the far end of the cantilever. What is the magnitude of the normal force (in Newton’s) that the wall exerts on the cantilever?
