Two parallel walls 6m apart are stayed together by a steel rod 2.5 cm diameter at a temperature of 80 0 c passing through washers and nuts at each end. Calculate the pull exerted by the rod when it has cooled to 220 C if, A) do not yield B) yield by 1.5 mm. Take the value of E & alpha for the alloy as 200 GPa and 11x10-6 /K .
