Parallel-Axis Theorem & Composite Sections

Inside this lesson

State the parallel-axis theorem I = I_c + A d^2 and define each term
Apply it to build a composite-section I table (one row per part)
Avoid the classic blunder: the transfer is from the centroidal axis only
Work a full I-section and verify the contribution of the flanges versus the web
