Parallel axis theorem of moment of inertia
http://physics.bu.edu/~redner/211-sp06/class13/class14_momentI.html WebSep 21, 2024 · Moments of inertia are always calculated relative to a specific axis, so the moments of inertia of all the sub shapes must be calculated with respect to this same axis, which will usually involve applying the parallel axis theorem. (10.4.1) I = ∑ i = 0 n ( I) i = ∑ i = 0 n ( I ¯ + A d 2) i. The method is demonstrated in the following examples.
