. Consider 3 bars of the same type of material. The bar is denoted as alloy 6061-T6.Bar 1, has a cross sectional area of 10 mm², and a length of 40 cm, Bar 2, has across sectional area of 20 mm² and a length of 40 cm, and Bar 3 has a crosssectional area of 10 mm², and a length of 70 cm. On a clearly labelled diagram show a plot of structural performance in tension for all three bars up until yield,and a second plot for material performance in tension for all three bars up until yield (assume realistic values). Show all units. You should show calculations to support your answer. Detail the manufacturing alumina.
