QUESTION 15 A bimetallic bar is made of two equal length steel and brass bars of same width firmly bonded together. The cross-sectional area of the brass bar is twice that of the steel bar. The Young's modulus of steel is twice that of brass. The coefficient of linear expansion of brass is twice that of steel. When the compound bar is subjected to a temperature rise of 50°C, what is the ratio of stress generated in steel to stress generated in brass?
