Matlab program code, future solution please!

"I want to reduce the volume of the robot leg as much as possible, while still being able to withstand the

load $($F$)$ well enough without yielding. Also, considering the possibility of future production, the length $($ L $)$ of the leg should be between $4$ m and $36$ m $,$ the width $(W)$ of the leg should be between $0\mathrm{.}1$ m and $6$ m $,$ and the length of the leg should be at least $10$ times the width of the leg!!"

Task Description: Geometry and Conditions of Target Structure $($Cantilever Beam$)$

ask $3.$ Write a report summarizing the contents of Task $1$ and Task $2.$

Request: Try to practice following the coding procedure as much as possible.

$($i$.$e$.,$ flowchart composition, function names, and input$/$output$/$coding methods.

$($thinking about the idea before actually starting coding$)$
