For a $\frac{5}{16}$ in$.$ Structural I unsanded panel, show how moment of inertia for stress perpendicular to the face grain could be determined for bending by loads acting normal to the panel face. Use APA assumptions and prove that in table $11\mathrm{.}4B$ the Inertia is $0\mathrm{.}002$ in$^\frac{4}{f}t.$
