Moment of inertia of i section formula

WebThe moment of inertia can be derived as getting the moment of inertia of the parts and applying the transfer formula: I = I 0 + Ad 2. We have a comprehensive article explaining … WebSince the cross-section is rectangular, the neutral axis must pass through the center of the section, and the distance c is in this case equal to one-half the depth, that is, 6 in. The moment of inertia may be found by the method given on page 77; or more easily by the formula for rectangular sections given in Table XII, on page 83. This ...
