Second moment of area circular section
WebThe second polar moment of area, also known (incorrectly, colloquially) as "polar moment of inertia" or even "moment of inertia", is a quantity used to describe resistance to torsional … WebIn order to calculate stress (and therefore, strain) caused by bending, we need to understand where the neutral axis of the beam is, and how to calculate the second moment of area for a given cross section. Let's start by imagining an arbitrary cross section – something not circular, not rectangular, etc.
