1. (5 points) Let's build a drawbridge! A simple drawbridge can be made from a large plank of wood and a rope that can be used to pull the bridge up and down. Here are two simple designs from Minecraft. Let's estimate the maximum load for each of these. In both of my pictures, A and B, the bridge is indicated by the blue line. The bridge is held in place by cables indicated by dashed lines. If a knight in full armor starts to move across the bridge, the knight will put the maximum stress on the bridge when it is at the very far end. Assume that the knight is at this point. A. Draw a Free Body Diagram for Bridge A (you can click on it and click edit). Include all of the forces on the bridge (only the bridge. The blue line). Assume that the bridge is a uniformi object whose center of mass is at the center. a. Make an estimate for the length of the bridge (in whatever units you want). The weight of the bridge is 2000 lbs. b. The cable (the dashed line) connected to the bridge can withstand 1500 lbs of Tension before breaking. Choose a pivot point and determine how heavy the knight can be before the bridge will collapse. B. Draw a Free Body Diagram for bridge in Situation B. Include all of the forces on the bridge. a. Use the same estimate for the length and weight of the bridge as before. Also, make an estimate for the angle and indicate it on your FBD. b. The cable in the bridge can withstand 1500 lbs before breaking. Choose a pivot point and determine how heavy can the knight be before the bridge will collapse. -0 19 es, A and B, the bridge is d by dashed lines. If a knight Eximum stress on the bridge -0 03 A B
