Practice objective / multiple choice question 16 from the 2018 City Guilds Model Questions Vol1 Engineering examination.
A composite rod consists of two materials joined in series. Material A has Young's modulus (200\ \text{GPa}\), length (0.5\ \text{m}\) and cross‑sectional area (10\ \text{mm}^2\). Material B has Young's modulus (100\ \text{GPa}\), length (0.3\ \text{m}\) and area (20\ \text{mm}^2\). A tensile force of (5\ \text{kN}\) is applied to the free ends. Assuming elastic behaviour, calculate the total elongation of the composite rod in millimetres.
