What is the maximum torque applied by the cable? (Give your answer in N m.) b. What is the torque due to the weight of the bridge? (Give your answer in N m.) c. How far can Lancelot ride out along the bridge before the cable breaks? (Give your answer in m.) Note: At his maximum distance, the torque from the cable will equal the torque from both the weight of the bridge and the weight of Lancelot.

Transcribed Image Text:Sir Lancelot rides slowly out of the castle and onto the 12.0 m long drawbridge.
Unbeknownst to him, the cable holding up the front end of the bridge will break under a
tension of 6800 N. The cable makes a 60.0° angle with the bridge. The bridge has a mass
of 200 kg. Lancelot, his horse, and his gear have a mass of 600 kg. In this problem we will
determine how far out along the bridge he can go before the cable breaks.
