A drum (mass m, radius r = 0.5 m) lies in a corner of a wall. The drum is connected to a freely suspended body (mass M) by a rope. The rope leads around a rounded corner of the wall (radius r₂ = 0.2 m). The static friction coefficient between drum and ground, drum and wall as well as rope and wall is μ。 = 0.5. Determine the maximum weight of the body M, up to which the system is still in equilibrium! μο m μο M
