On a day when the temperature is 20.0°C, a concrete walk is poured in such a way that its ends are unable to move.

(a) What is the stress in the cement when its temperature is 50.0°C on a hot, sunny day?

(b) Does the concrete fracture? Take Young's modulus for concrete to be 7.00 × 10⁹N/m²and the compressive strength to be 2.00 × 10⁷N/m².
