Raising a Ladder. A ladder carried by a fire truck is 20.0  m long. The ladder weighs 2800  N and its centre of gravity is at its centre. The ladder is pivoted at one end (A) about a pin (Fig. 11.22); 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 F have to just lift the ladder off the suppor

A ladder carried by a fire truck is 20.0 m long. The ladder weighs 3400 N and its center of gravity is at its center. The ladder is pivoted at one end (A) about a pin (Fig. E11.5); 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 F exerted by the piston makes an angle of 40^∘with the ladder. What magnitude must F have to just lift the ladder off the support bracket at B? Start with a fr
