4 1 point The graph below shows the force-extension curve obtained during the tensile testing of an aluminium alloy. The specimen has a rectangular cross section with the dimensions 1.93 mm x 5.07 mm. Calculate the ultimate tensile stress (in MPa). Aluminium Alloy 3 Al Alloy 2.5 N N Force (kN) 1.5 1 0.5 0 0 0.5 1 1.5 2.5 3 3 3 3.5 N 2 Extension (mm) Type your answer O E
