1. A uniform crane arm (length L) is attached to the rest of the crane by a frictionless axle at its lower end, and it is at an angle of 55.0° from horizontal (see figure). It is held in place by a cable that is attached 3.00 meters from its upper end, at an angle of 25.0° from the crane arm. A 2750-N load of bricks hangs from the upper end of the beam, at the end of a light cord that is 2.20 meters long. The tension in the cable is 5950 N and the crane arm weighs 1510 N. a. Find the length of the crane arm (L). b. Find vertical component of the force that the axle exerts on the beam (magnitude and direction). Find the horizontal component of the force that the axle exerts on the beam (magnitude and direction). C. Cable 25° Axle 55° 3.0 m 2.2-m cord Bricks

Question
1. A uniform crane arm (length L) is attached to the rest of the crane by a frictionless axle at its lower end, and it is at an angle of 55.0⁰ from horizontal (see figure). It is held in place by a cable that is attached 3.00 meters from its upper end, at an angle of 25.0° from the crane arm. A 2750-N load of bricks hangs from the upper end of the beam, at the end of a light cord that is 2.20 meters long. The tension in the cable is 5950 N and the crane arm weighs 1510 N. a. Find the length of the crane arm (L). b. Find vertical component of the force that the axle exerts on the beam (magnitude and direction). Find the horizontal component of the force that the axle exerts on the beam (magnitude and direction). C. Cable 25° Axle 55° 3.0 m- 2.2-m cord Bricks
