The crown of the cogwheel has a mass m = 30 kg, the radius of inertia ρ = 0.25 m, the radius of the dividing circle R = 0.3 m, the radius r = 0.15 m. Determine the force F of one spring if the angular acceleration of the crown ε = 40 Rad / c2, and the force in the meshing is P = 800 N. Springs are the same. (Answer 251)
