A composite bar made up of aluminium bar and steel bar, is firmly held between two unyielding
supports as shown in Fig. 4.22.
Fig. 4.22
An axial load of 200 kN is applied at B at 47°C. Find the stresses in each material, when the
temperature is 97°C. Take Ea = 70 GPa ; Es = 210 GPa ; aa = 24 × 10–6/°C and as = 12 × 106/°C.
[Ans. 60.3 MPa; 173.5 MPa]
