Programming: develop a program function using any scientific software $($e$.$g$.,$ EXCEL,

MathCAD, Matlab, Mathematica, etc.$).$ Please upload your function$/$program on

Canvas along with a brief instruction how to use it$.$ The function should have the

following features:

a$)$ Given series of ${}_1$ and ${}_3,$ it will find the best fit $c$ and $.$

b$)$ Given $c$ and $,$ it plots the failure envelope on $-$ coordinates;

c$)$ Given the stress state at a point, it plots a Mohr$-$Circle to represent the stress

state;

d$)$ Given $c,,$ and normal stress ${}_1,$ it gives the shear strength at failure;

e$)$ Given $c,,$ and stress state at a point, it determines whether the Mohr$-$Circle

intersects with the failure envelope. If yes, calculate the shear strength when the

normal stress is the major principle stress; if no$,$ calculate the maximum major

principle stress while the minor principle stress remains the same.
