WebThe moment of inertia with respect to an axis passing through the center of a disk in its plane is 1 4 m r 2. We now use the parallel axis theorem and add m r 2 to each moment of inertia to get the total moment of inertia for the system you are describing. This gives I = 2 m r 2 + 1 2 m r 2 + 1 4 m r 2 as required. WebFeb 20, 2024 · The total moment of inertia is the sum of moments of inertia of the merry-go-round and the child (about the same axis). To justify this sum to yourself, examine the definition of I: (10.3.12) I = 28.13 k g ⋅ m 2 + 56.25 k g ⋅ m 2 = 84.38 k g ⋅ m 2. Substituting known values into the equation for α gives.
