Answer:
An intense property is a physical attribute of a system that is independent of the size of the system or the quantity of material it contains. An extensive property of a system, on the other hand, is dependent on the size of the system or the amount of material in it.

Answer:
The strength coefficient is
and the strain-hardening exponent is ![0.435](https://tex.z-dn.net/?f=0.435)
Explanation:
Given the true strain is 0.12 at 250 MPa stress.
Also, at 350 MPa the strain is 0.26.
We need to find
and the
.
![\sigma =K\epsilon^n](https://tex.z-dn.net/?f=%5Csigma%20%3DK%5Cepsilon%5En)
We will plug the values in the formula.
![250=K\times (0.12)^n\\350=K\times (0.26)^n](https://tex.z-dn.net/?f=250%3DK%5Ctimes%20%280.12%29%5En%5C%5C350%3DK%5Ctimes%20%280.26%29%5En)
We will solve these equation.
plug this value in ![350=K\times (0.26)^n](https://tex.z-dn.net/?f=350%3DK%5Ctimes%20%280.26%29%5En)
![350=\frac{250}{(0.12)^n}\times (0.26)^n\\ \\\frac{350}{250}=\frac{(0.26)^n}{(0.12)^n}\\ \\1.4=(2.17)^n](https://tex.z-dn.net/?f=350%3D%5Cfrac%7B250%7D%7B%280.12%29%5En%7D%5Ctimes%20%280.26%29%5En%5C%5C%20%5C%5C%5Cfrac%7B350%7D%7B250%7D%3D%5Cfrac%7B%280.26%29%5En%7D%7B%280.12%29%5En%7D%5C%5C%20%20%5C%5C1.4%3D%282.17%29%5En)
Taking a natural log both sides we get.
![ln(1.4)=ln(2.17)^n\\ln(1.4)=n\times ln(2.17)\\n=\frac{ln(1.4)}{ln(2.17)}\\ n=0.435](https://tex.z-dn.net/?f=ln%281.4%29%3Dln%282.17%29%5En%5C%5Cln%281.4%29%3Dn%5Ctimes%20ln%282.17%29%5C%5Cn%3D%5Cfrac%7Bln%281.4%29%7D%7Bln%282.17%29%7D%5C%5C%20n%3D0.435)
Now, we will find value of ![K](https://tex.z-dn.net/?f=K)
![K=\frac{250}{(0.12)^{0.435}}\\ \\K=\frac{250}{0.40}\\\\K=625](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B250%7D%7B%280.12%29%5E%7B0.435%7D%7D%5C%5C%20%5C%5CK%3D%5Cfrac%7B250%7D%7B0.40%7D%5C%5C%5C%5CK%3D625)
So, the strength coefficient is
and the strain-hardening exponent is
.
