Product description
3.56. A uniform disk of radius R = 20 cm is free to rotate around a horizontal z-axis perpendicular to the plane of the disk and passing through the point O (see. Ris.nizhe). Determine the angular and linear velocity of a point in the disc at the time of passage through the equilibrium position. The calculations are performed for the following cases: 1) a = b = R, α = π / 2; 2) a = R / 2, b = 0, α = π / 3; 3) a = 2R / 3, b = 2R / 3, α = 5π / 6; 4) a = R / 3, b = R, α = 2 π / 3.
