It can be seen from the above derivation process that the value of the moment of inertia varies depending on the reference axis.
Webb5 feb. 2024 · I was reading about moment of inertia on Wikipedia and thought it was weird that it had common values for shapes like tetrehedron and cuboids but not triangular prisms or triangular plates, so I tried working it out myself. I will post my attempt below, but for some reason I cannot find any source online that confirms or denies my solution. WebbEngineering. Mechanical Engineering.
