A 2.5m steel rod with a cross sectional area of 1250m^2 is secured between rigid supports at both ends. If there is no stress of 30°C, E = 200000MPa. (a)Compute the stress when the temperature drops to 0°C, if it has a coefficient of thermal expansion of 0.0000117 m/m°C. (b)Compute the strain of the rod if the rod supports yield by 0.800mm as temperature drops. (c)Compute the stress in the rod if the support yield and moves together a distance of 0.800mm as the temperature drops.
