17.4.4
A material point with a mass m = 0.5 kg rotates under the action of a pair of forces with a moment M about the axis OO1. Determine the modulus of the dynamic reaction of the bearing O1 at the time when the angular velocity ω = 5 rad / s, and the angular acceleration ε = 40 rad / s2, if the size l = 0.15 m (Response 7.08)
