Question: to determine an ibeams maximum bending moment moment of inertia...
To determine an I-beam’s maximum bending moment, moment of inertia using the parallel-axis theorem, and the maximum stress at a given location using the flexure formula.
As shown, I-beam ABC supports a sign having a mass of S = 11 kg . The I-beam is 700 mm long and is further supported by a rod that is attached 460 mm from the wall. Assume that all forces acting on the I-beam act along its centroid and that the I-beam’s weight is negligible. Let the dimensions of the I-beam be w = 50 mm , g = 20 mm , h = 70 mm , j = 15 mm , c = 140 mm
