To find the combined mass of several objects, we simply add their masses. To find the combined moment of inertia of several object, we need to individually calculate the moment of inertia for each object and add their moments of inertias. Consider a platform (solid disk or cylinder) of mass 1.210 kg and radius 0.7400 m which is rotating about its center. There are two objects placed on it. Treat these two objects as point objects. platform_AB-01.png Object A has a mass of 1.200 kg and sits a distance 0.5920 m from the axis of rotation. Object B has a mass of 0.9480 kg and sits a distance 0.1998 m from the axis of rotation. What is the moment of inertia of the platform? Tries 0/10 What is the moment of inertia

What is the moment of inertia of Object A? Tries 0/10
What is the moment of inertia of Object B? Tries 0/10
What is the combined moment of inertia of all three objects
