Solution of task 5.6.5 from the collection of Kepe OE

5.6.5
The force F = 2Q = 120N, applied to the pulley, is balanced by a pair of forces with a moment M = 18 N • m. Having formed the equation of the moments of forces about the axis Ox, determine the reaction YA of the bearing A, if the radius of the pulley r = 0.3 m, a = 0.3 m and the force F || Q || OU. (Answer 90)
