WebTherefore the first moment of the cross section about its neutral axis must be zero. Therefore the neutral axis lies on the centroid of the cross section. Note that the neutral axis does not change in length when under bending. It may seem counterintuitive at first, but this is because there are no bending stresses in the neutral axis. has highlight magazine gone wokeWebThere are three formulas to calculate the moment of inertia for a cylinder, each used depending on what axis the cylinder rotates around, as depicted in the diagram above.
