A uniform bar of length 3.3 m and mass 4.1 kg is attached to a wall through a hinge mechanism which allows it to rotate freely. The other end of the bar is supported by a rope of length 6 m which is also connected to the wall as shown above. What force in N does the wall exert vertically on the bar through the hinge? (Consider an upward force as positive and a downward force as negative.)
