WebThe elastic section modulus, Sx, is a single parameter that measures a cross section’s strength in bending. For symmetrical sections, such as those shown in Figures 1.48a and 1.48b: (1.10) For the circular shapes, Sx = Ix / R ( Figures 1.48c and 1.48d ). In each case, the moment of inertia is divided by half the cross-sectional height, or ... WebFigure 10.25 Calculation of the moment of inertia I for a uniform thin rod about an axis through the center of the rod. We define dm to be a small element of mass making up the rod. The moment of inertia integral is an integral over the mass distribution. However, we know how to integrate over space, not over mass.
