The drum 1 of radius r = 20 cm under the action of a pair of forces with a moment M rotates with a constant angular acceleration ε = 2 rad / c2. Determine the reaction modulus in the hinge O, if the sliding friction coefficient of the body 2 along the plane f = 0,1, and the mass of the cargo 2 is 4 kg. The weight of the drum should be neglected. (Answer 5.52)
