City Guilds Model Questions Vol1 2017 Engineering Question 36
Practice objective / multiple choice question 36 from the 2017 City Guilds Model Questions Vol1 Engineering examination.
A composite bar of length 500 mm consists of two materials placed side‑by‑side (parallel arrangement) and subjected to a tensile load of 12 kN. Material A has Young's modulus \(E_A = 200\) GPa and cross‑sectional area \(A_A = 30\) mm\(^2\). Material B has \(E_B = 100\) GPa and area \(A_B = 20\) mm\(^2\). Assuming the load is shared proportionally to the axial stiffness of each material, determine the total extension of the bar (in mm).
