Chapter 11, Problem 11.11P

A $\text{4}-\text{in}.$ -by- $\text{8}-\text{in}$ . short wood post is reinforced on all four sides by ASTM $\text{A36}$ steel plates. Two plates are $\text{4 in}$ . By $\frac{1}{8}$ thick and two plates are $\text{8 in}$ . By $\frac{1}{4}$ thick. Using nominal dimensions, calculate the maximum axial compressive load that the member can safely carry. The wood is southern pine. The allowable stress is $\text{2}0,000$ psi for the steel.
