Chapter 7, Problem 35P

To determine

To write:

AMATLAB user-defined function that calculates the area moment of inertia $I_{x_c}$ of a U-beam about the axis that passes through its centroid (shown in the figure) by using $\text{Ixc}=\text{IxcTBeam(w,h,t,d)}$ as function name and arguments; a code that calculates the coordinate $y_c$ for a beam with $w=12\text{in}$, $h=8\text{in}$ $d=2\text{in}$ and $t=0.75\text{in}$ using the above function.(Use the user-defined function $\text{centroidU}$ from the previous problem as a sub-function inside $\text{IxcTBeam}$ .)
