National Exams — December 2016 · 07-Mec-A7 Advanced Strength of Materials. Open-book, 3 hours. Eight problems of equal value; any five constitute a complete paper. All eight are solved as a study resource.

Reference texts. Boresi & Schmidt, Advanced Mechanics of Materials, 6th ed.; Ugural & Fenster, Advanced Strength and Applied Elasticity, 4th ed.; Hibbeler, Mechanics of Materials, 10th ed.; Timoshenko & Gere, Theory of Elastic Stability.

Check: the figure for Question 1 labels the applied load P = 7000 N, whereas the printed text reads “7800 N”. The drawn value on the exam figure governs, so 7000 N is used throughout.
