A homogeneous ice rink 2 with a weight of 4 kN is connected to the body 1 by an inextensible yarn. Radius R = 0.5 m, coefficient of rolling friction? = 0.005 m, the moment of the pair of forces M = 50 N · m. Determine the largest weight of the body 1, at which it begins to slide, if the sliding friction coefficient for the roller and the body is f = 0.2. (Answer 150)
