Three point objects with masses m1 = 3.0 kg, m2 = 1.2 kg, and m3 = 2.7 kg are arranged in the configuration shown in the figure. The distance to mass m1 is d1 = 24 cm and the distance to mass m3 is d3 = 43 cm. The distances are measured from the axis O. What is the combined moment of inertia I for the three point objects about the axis O? I =
