Ouestion $4$: Conditional Statements

Write a MATLAB program to determine the stress category of a material. The stress, $,$ is given as:

$=\frac{F}{A}$

where $F$ is the force $($input by the user$),$ and $A$ is the cross$-$sectional area $($input by the user$).$ Categorize the stress level based on the following conditions:

$<mn>5</mn><mn>0</mn>$ : Safe

$50<mn>1</mn><mn>0</mn><mn>0</mn>$ : Warning

$100$ : Failure

Question $5$: Loops

Write a script to calculate the sum of the series:

$S=1+2+3+$cdots$+N$

$N$ is the input from user.

Question $6$: Functions

Create a function in MATLAB to compute the maximum deflection of a beam using the equation:

$=\frac{5w{L}^4}{384EI}$

where:

$w$: Load per unit length $(\frac{N}{m}).$

$L$ : Beam length $($ m $).$

E: Modulus of elasticity $(Pa).$

I: Moment of inertia $(m^4).$

Prompt the user for the inputs and display the result.
