Use Eq$.(3\mathrm{.}4)$ to calculate the location of the centroid of the cross$-$sectional

area. Then use Eq$.(3\mathrm{.}3)$ to calculate the area moment of inertia of the cross$-$

section with respect to the neutral axis.

Use Eq$.(3\mathrm{.}1)$ to calculate the maximum allowable load Pmax that can be applied

to the beam given an allowable bending stress of $70$ MPa. Check your results

with the instructor before starting the experiment.
