Transcribed Image Text:

A steel tube as shown in figure, is fitted with an equal length of an aluminium rod (Total Area of aluminium area of steel 200 mm²) at room temperature at stress free condition. If the temperature is raised by 80 °C, then the load in aluminium bar is = = Take, E₂70 GPa, da = 25 x 10⁰ °C Es = 210 GPa, as = 12.5 × 10° /°C Steel (a) 21 kN (c) 15.8 kN Aluminum (b) 18 kN (d) 10.5 kN A steel tube as shown in figure, is fitted with an equal length of an aluminium rod (Total Area of aluminium area of steel 200 mm²) at room temperature at stress free condition.
