The drawbridge is now slowly lowered to the ground and comes to rest in a horizontal position as shown in the picture above. At this point in time the tension in the cable is zero and all of the weight of the bridge is supported by the ground at the right end and the pivot at the left end. A castle has a 4.0 m long drawbridge that is currently raised as shown above. The mass of the drawbridge is 300.0 kg. The angle = 90.0 and the angle = 45.0. The support force of the ground can be considered to be applied 0.5 m from the right end of the drawbridge. The support force at the pivot is applied at the left end of the drawbridge.
