Q2: A bar of steel, having a rectangular cross-section of 7.5 cm by 2.5 cm (see figure below), carries an axial tensile load of 180 kN. Given that, Young's modulus, E, is 200 GN/m2 and Poisson's ratio, v, is 0.3. Estimate: 1- The normal stress in the bar. 2- The change in the length, if its original length before the load is applied is 100 cm. 3- The lateral strain. 4- The decrease in the length of the sides of the cross-section.

Question
Q2: A bar of steel, having a rectangular cross-section of 7.5 cm by 2.5 cm (see figure below), carries an axial tensile load of 18O kN. Given that, Young's modulus, E, is 200 GN/m2 and Poisson's ratio, v, is 0.3. Estimate: 1- The normal stress in the bar. 2- The change in the length, if its original length before the load is applied is 100 cm. 3- The lateral strain. 4- The decrease in the length of the sides of the cross-section.
