PROBLEM 9.194 For the 2-kg connecting rod shown, it has been experimentally determined that the mass moments of inertia of the rod with respect to the center-line axes of the bearings AA′and BB′are, respectively, 278 gmAAI′=and 241 gmBBI′=. Knowing that 290 mmabrr+=, determine (a) the location of the centroidal axis GG′(b) the radius of gyration with respect to axis GG′SOLUTION (a) Have 2290 mmAAGGaabIImr′′=++=0.29 m=and 2BBGGbIImrSubtracting ( )22BBAAbaIrr−=−( ) ( )( )24178 g m
