. A dog-bone specimen of aluminium was pressed out of 5 mm sheet. The gauge length was 65 mm with a width of 13 mm. The sample was tested in

tension, with the load elongation characteristics shown below: i.Plot the data as engineering stress versus engineering strain ii.Calculate the Young's modulus ii.Determine the yield strength t a strain offset of 0.002 iv.Determine the tensile strength of this alloy Estimate the toughness of this alloyV. b) A specimen 750 mm long is exposed to a tensile stress of 60 MPa at 925 °C, to induce a creep rate of 104 h².Determine the new length after 1000 hours assuming both the instantaneous and primary elongation is 1.5 mm.
