Question $3$

A beam with a T section has a flange with $($base $=0\mathrm{.}05m$ and height $=0\mathrm{.}01m)$ and a web with $($base

$=0\mathrm{.}01m$ and height $=0\mathrm{.}1m).$ Respond to the following questions:

Question $3$a:

Find the centroid $($measured from the bottom edge of the section$).$

Question $3$b:

Calculate the second moment of area about the $x-x$ axis and $y-y.$

Question $3$c: Find the maximum bending moment for this section. If the maximum bending

stress is $15$ MPa $.$
