The following figure shows a 4 m bar attached to the wall through a hinge that rotates freely, but is tied to the wall at its other end so that the system is in equilibrium. If the bar weighs 40 N and the tension in the rope is 20 N, find the angle of inclination θ (theta) that the bar makes with the x-axis and the magnitude of the reaction force at the hinge.
