Raising a Ladder. A ladder carried by a fire truck is 20.0 m long. The ladder weighs 2800 N and its center of gravity is at its center. The ladder is pivoted at one end (A) about a pin (Fig. E11.5); 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 8.0 m from A , and the force F⃗ exerted by the piston makes an angle of 40^∘ with the ladder. What magnitude must F⃗ have to just lift the ladder off the suppor
