Two bars are untressed and have lengths of 25cm and 30cm at 20^(@)C as shown in Figure. Bar (1) is of aluminium and bar (2) is of steel. The croos-sectional area of bars are 20cm^(2) for aluminium and 10cm^(2) for steel. Assuming that the top and bottom supports are rigid, stress in (N)/(mm^(2)) when the temperature is 70^(0)C . (Nearly) ( Y_(a)=0.70xx10^(5)N//mm^(2)Y_(s)=2.1xx10^(5)N//mm^(2).alpha_(a)=24xx10^(-6//0)C and alpha_(s)=12.xx10^(-6//0)C )
