A tensile test is conducted on a rectangular iron bar with dimensions of $4\mathrm{.}8mmx15\mathrm{.}9mm$ and a initial

length of $75\mathrm{.}00mm.$ The results obtained from the experiment are given in the table below. Using these

data, answer the following questions.

j$)$ If the material is loaded up to $30,000N$ and then unloaded, calculate the modulus of elasticity, yield

strength, tensile strength, and ductility for the next loading condition.

k$)$ Draw the true stress$-$strain curve along with the engineering stress$-$strain curve.CAN YOU PLEASE DRAW THE CURVE
