Moment of inertia of n sided polygon

WebThis paper studies the in-plane free vibration of axially functionally graded (AFG) circular arches with non-uniform cross-section. The geometric and material properties of circular arches with regular polygon cross-section vary symmetrically about the mid-arc along the axial direction in quadratic polynomial form. The governing differential equations of the … Web12 jun. 2024 · The idea of the moment of inertia is as follows. We want to find a relation between the angular momentum of a rotating body (can be composed of many particles) and its angular velocity. Essentially, we want to find something like this: →L = (something) ∗ →ω The question is what is this (something).
