A connecting rod is supported by a knife-edge at point A: the period of its small oscillations is observed to be 0.87 s. The rod is then inverted and supported by a knife edge at point Band the period of its small oscillations is observed to be 0.78 s. Knowing that rn + rb= 10 in., determine (a)the location of the mass center G, (b)the centroidal radius of gyration k.
