In Fig. 10-60, two particles, each with mass m = 0.85 kg, are fastened to each other, and to a rotation axis at O, by two thin rods, each with length d = 5.6 cm and mass M = 1.2 kg. The combination rotates around the rotation axis with the angular speed `omega=0.30rad//s`. Measured about O, what are the combination's (a) rotational inertia and (b) kinetic energy?
