On a day that the temperature is 20. 0"�, a concrete walk is poured in such a way that the ends of the walk are unable to move. Take Young’s modulus for concrete to be 7.00 × 102 �/m2 and the compressive strength to be 2.00x109 N/m2 . (a) What is the stress in the cement on a hot day of 50. 0"�? (b) Does the concrete fracture? (4%)
