25-Nav-A4 Ship Structure and Strength of Ships: May 2016

National Exams — May 2016 — 98-Nav-A4 Ship Structure and Strength of Ships. Three-hour, closed-book exam (no notes permitted); Casio/Sharp non-programmable calculator and simple drawing equipment allowed. Format: six compulsory questions, marks indicated per sub-part, totalling 100; some formulae (beam bending relations, section modulus, shear flow, deflection/slope tables) and a Normal (cumulative) distribution table are supplied at the end of the exam and are used directly below. All six are solved in full.
