The rectangular plate rotates in a horizontal plane under the action of a spring and force F = 50Н. In this position, the angular acceleration is e = 50 rad / s2. The moment of inertia of the plate relative to the axis of rotation is 0.02 kg • m2, l = 0.1 m. Determine the modulus of the reaction of the spring. (Answer 110)
