The hoop is suspended at the point A and is free to swing in its own vertical plane as shown in Figure 11.20. Using the angles 1 and 2 as generalized coordinates, solve for the normal frequencies of small oscillations, and find and describe the motion in the corresponding normal modes. [Hint: The KE of the hoop is 167, where I is its moment of inertia about A and can be found using the parallel axis theorem.] 02 m Figure 11.20 Problem 11.26arrow_forward
