a. A tensile bar stretches an amount = P.L/A-E where P is the applied load, L is the length of the bar, A is the cross- sectional area, and E is Young's Modulus. The bar has a circular cross section. Given a load of 30 kN, a length of 80 cm, a diameter of 6 mm, and a Young's Modulus of 207 GPa, calculate the deflection in mm. (10 Marks) a.
