Question
(a) A bar $2\text{ cm} \times 4\text{ cm}$ in cross-section and $40\text{ cm}$ long is subjected to a radial tensile load of $70\text{ kN}$. It is found that the length increases by $0.176\text{ mm}$ and lateral dimension of $4\text{ cm}$ decreases by $0.0044\text{ mm}$. Find :
(i) Young's modulus
(ii) Poisson's ratio
(iii) Change in volume of the bar
(iv) Bulk modulus. [10]
(b) Draw stress-strain diagram for mild steel and explain it briefly. [10]
