A steel bar is 2.4 meters long and 5 centimeters in diameter. A force of 8 kN is then applied to the bar. The bar under the applied force is now 2.448 meters long. Calculate the following for the bar: a) engineering stress, b) engineering strain, c) true strain, d) Young's modulus, e) What additional information would you need to calculate the true stress? f) What is unrealistic about this problem? Could you change one word in the problem to make the problem realistic?
