This simple, easy-to-use moment of inertia calculator will find moment of inertia for a circle, rectangle, hollow rectangular section (HSS), hollow circular section, triangle, I-Beam, T-Beam, L-Sections (angles) and channel sections, as well as centroid, section modulus and many more results. The beam has tension steel of A s = 4-#10 bars placed in one layer f y = 60 ksi, and compression steel of A s ′ = 2-#7 bars, f s ′ = 60 ksi, effective cover d′ of 2.5 in. The mid-span deflection can be calculated by solving two simultaneous equations for the rotations at each beam end. Calculate SF & BM for Cantilever, Deflection & Slope Calculator for Cantilever
