Name:

CCE $203-$ HW Centroid & Moment of Inertia

Date:

A built$-$up steel beam is constructed of a W $1250$ shape with a $10$ inch wide, $0\mathrm{.}5$ inch tall

plate of the same material on the top of it$.$

a$)$ Use this information and the table above to calculate the centroid of the built$-$up beam,

measured from the bottom of the beam. $($Note: the height of the I$-$beam is labeled as

Depth on the table.$)$

$\frac{?}{\text{b}\text{a}\text{r}}(y)=$

b$)$ What is the moment of inertia of the beam about the centroid of the cross section?
