Question

A composite bar made of two aluminium bars is firmly held between two yielding supports as shown above. An axial load of 200KN is applied at C at 50°C. If there's a gap of 60mm between the points B and C of the bar, find the (i) stress in the bar. (ii) stress in bar AB. (iii) stress in bar CD. when the temperature is 103°C. Take $E_a = 70GPa$ $\alpha_a = 24 \times 10^{-6}/°C$.

Step 1

An axial load of 200 kN is applied at point C. There is a gap of 60 mm between points B and C. We are given the initial temperature as 50°C and the final temperature as 103°C. We need to find the stress in the bar (presumably referring to the stresses in bars AB Show more…
