Two parallel walls, 8 m apart, are stayed together by a steel rod of 20 mm diameter passing through metal plates and nuts at each other. The nuts are screwed upto the plate while the bar is at a temperature of 400°C. If the total yielding at the two ends is 5 mm, the pull exerted by the bar after it has cooled to 300 °C, will be kN. (Take a = 12 x 10-6 °C-1, E = 2 × 105 N/mm²)
