Solution of the D 7 (reference 1) Option 20 Dievskaya V

Termehu Dievskaya VA task 1 task Dynamics 7 (D7) on the theme "small oscillations of mechanical systems":
D7 ACTIVITY 1 - FREE VIBRATIONS: To shown in Scheme 1-30 mechanical systems to determine the natural frequency of oscillation. Mechanical systems shown in the diagrams in the equilibrium position, can perform free oscillations, rotating around a horizontal axis z, passing through the fixed point O. systems consist of rigidly connected with one another telephone: thin homogeneous cores 1 and 2 or the homogeneous plate 3 and point loads 4. The weight of 1 m length of the rods is 25 kg, the weight of 1 m2 plate - 50 kg, the weight of the point of cargo - 20 kg. Elastic elements have stiffness coefficient c = 10 kN / m. Dimensions cha stey system shown in meters.
