A glass window is to be fit in an aluminum frame. The temperature on the working day is 40^@C and the glass window measures exactly 20 cm xx 30 cm. What should be the size of the aluminum frame so that there is no stress on the glass in winter even if the temperature drops to 0^@C ? Coefficients of linear expansion for glass and aluminum are 9.0 xx 10^(-6)C^(-1) and 24xx10^(-6)C^(-1) respectively.
