Q5 An aluminium rod with the following geometrical dimensions (ø 12.8 mm and 50.8 mm length) is investigated using a quasi-static tensile test. With the given data for load and

extension, complete parts (a) through (g). (a) Plot the data as engineering stress versus engineering strain. (4 marks) (b) Compute the modulus of elasticity. (2 marks) (c) Determine the yield strength at a strain offset of 0.002. (2 marks) (d) Determine the tensile strength of this alloy. (1 mark) (e) What is the approximate ductility, in percent elongation? (2 marks) (f) Compute the modulus of resilience. (2 marks) (g) What is the approximate hardness of the rod (in HB)? (2 marks)
