35. Write a user-defined function that determines the coordinate of the centroid of the Ishaped cross-sectional area shown in the figure.

For the function name and arguments, use yc =

centroidI(w,h,d,t), where the input arguments w, h,

d, and t are the dimensions shown in the figure and the output argument yc is the coordinate .

Use the function to determine for a beam with in., in., in., and in.
