EXERCISE 7.59 Slender bar BC is suspended from pivot A by a cable. A precessional motion about the vertical is induced. It is desired to investigate the ensuing motion under the assumption that the cable remains taut, in which case it forms angle rela- tive to the vertical. The bar lies in the same vertical plane as the cable, at angle from vertical. Derive the differential equations of motion governing , 0, and the precession angle v. B A Exercise 7.59
