![Bar BC is made of brass which has E = 90 GPa, a = 20 × 10¯6 /°C, and A = 500 mm? Bar ED is made of steel
which has E = 200 GPa, a = 12 × 10–6 /°C, and A = 250 mm². Assume that bar ABD is rigid.
The temperature of BC is decreased by 25 °C and the temperature of DE is increased by 25 °C, causing bar ABD to
rotate clockwise.
