A square timber column, 10 in. by 10 in. in cross section, is reinforced on all four sides by copper plates, each plate being 10 in wide and “t” in thick. Determine the smallest value of “t” for which the column can support an axial load of 560 kips if the working stresses are 1250 psi for timber and 17 ksi for copper. The moduli of elasticity are 1.5 × 10^6 psi for timber and 17 × 10^6 psi for copper.
