502 Lagrangian and Hamiltonian Dynamics Chap. 12 12.6. A point mass m is constrained to move on a circle of radius R and acted on by a force F, as shown in Fig. P12.6. Calculate the generalized force and the virtual work done considering (a) s as a se eralized coordinate, and (b) 0 as a generalized coordinate.
