National Exams May 2016 — 04-BS-6: Mechanics of Materials (3 hours, closed book, one hand-written aid sheet permitted). Any FIVE of the eight questions constitute a complete paper on the official exam; every question is answered below. A W-shape section-property table is attached at the end of the official exam; it is a red herring here — every question below supplies its own built-up or standard section, and Question 2 cites the CISC-standard W610×125 properties directly.

Reference texts: Hibbeler, Mechanics of Materials, 10th ed. (composite beams, deflection by integration, combined loading, transformation of stress, columns, torsion, shear/moment diagrams); CISC Handbook of Steel Construction (W-shape section properties).
