Two identical homogeneous rods rotate about the Oy axis, having at this time the angular velocity ω = 10 rad / s and the angular acceleration ε = 100 rad / s2. Determine the modulus of the principal vector of inertia forces of the rods, if the mass of each rod is 2 kg, and the length l = 0.4 m (Answer 80)
