I want to see how it's done.

Problem $4$ Points $(25="6(3+3)"4+4+6(3+3)""5")$

The graphs below show the tensile test lab results for two materials $($A and B$).$ Use these graphs to answer the following questions.

$($a$)$ Which of the materials is relatively more "ductile" than the other? Explain your answer.

$($b$)$ Calculate $\%$elongation for both materials.

$($c$)$ Find the "yield strength" for both materials on the graph. Write down the approximate value$/$number you get from the stress$-$strain diagram.

$($d$)$ Find the "Ultimate Tensile Strength" for both materials on the graph. Write down the approximate value$/$number you get from the stress$-$strain diagram

$($e$)$ Which part of the stress$-$strain diagram will you use to calculate the modulus of elasticity? Calculate approximate value the modulus of elasticity.
