On the diagram below add forces to show all the forces acting on the drawbridge and the line of action and lever arm for each force. The drawbridge is uniform with mass M; the knight is represented with mass m and is located at - L, one quarter of the way across the bridge. You may draw and use the components of the hinge force. Pick the hinge at the pivot to be your axis (show this), and write the required equations for equilibrium. pivot OFE 120m % T cos e mg Solve algebraically for the tension T' in the chain supporting the right end. After you have an algebraic solution, plug in the following numbers to find the tension: mass of knight (including the horse) = 600 kg; mass of drawbridge-1100 kg; 0 = 50. To finish the problem, use the force equations for horizontal and vertical forces and solve for the components of the hinge force. Also find the angle of the hinge force and compare to 0. Are these equal?
