A ladder of length L = 20.0 m is carried by a fire truck. The ladder has a weight of 2880 N and its center of gravity is at its center. The ladder is pivoted at one end (A) about a pin; you can ignore the friction torque at the pin. The ladder is raised into position by a force applied by a hydraulic piston at C. Point C is a distance 8.00 m from A, and the force F exerted by the piston makes an angle of theta = 40.0 degrees with the ladder.
What magnitude must F have to just lift the ladder off the support bracket at B?
**Imagine a firetruck carrying a horizontal ladder placed on top:
b is close to the center of mass of the ladder but more to the front of the truck
