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. 12.0 m 60.0⁰
Rotational Equilibrium And Rotational Dynamics
In physics, the state of balance between the forces and the dynamics of motion is called the equilibrium state. The balance between various forces acting on a system in a rotational motion is called rotational equilibrium or rotational dynamics.
Equilibrium of Forces
The tension created on one body during push or pull is known as force.
a. What is the maximum torque applied by the cable? (Give your answer in N m.)
b. 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.
