17 11 Two Uniform Circular Plane Wheels Of Equal Mass 1 00 Kg Are Mutually Pivoted About A Horizontal Axis A Perpendic 2 (9.14 KiB) Viewed 54 times
17.11 Two uniform, circular plane wheels of equal mass 1.00 kg are mutually pivoted about a horizontal axis A, perpendicular to both bodies and passing through their centers of mass, as shown in Fig. 17-8. The radii of gyration* R of the two bodies are also equal: R = 0.20 m. Body 2 is pivoted about a fixed horizontal axis B, a distance R from its CM. Initially, body 2 is motionless and body 1 is rotating at angular velocity wo about the common axis. A small latch pin C, fixed in body 1, suddenly drops into a hole in body 2, stopping their relative motion. It is observed that the resulting pendular motion of the system has an amplitude of 90° each side of the vertical. Find wo. .B Wo A .C A Figure 17-8 B * The radius of gyration R, about a given axis, of a mass M, having moment of inertia I about that axis, is defined to be R = √√I/M.
