a$)$ Construct an engineering stress vs$.$ strain plot $($landscape orientation, full scale of paper$)$

b$)$ Determine the modulus of elasticity, E$,$ with proper units

c$)$ Determine the yield strength with proper units

d$)$ Determine the ultimate tensile strength with proper units

e$)$ Determine the ductility, in percent elongation $(\%$EL$)$

f$)$ Determine the modulus of resilience with proper units

Load $($N$)$ Length $($mm$)$
