QUESTION:

A block of 10-in. length and \(1.8 \times 1.6-\mathrm{in}\) cross section is to support a centric compressive load P. The material to be used is a bronze for which \(E=14 \times 10^{6}\) psi. Determine the largest load that can be applied, knowing that the normal stress must not exceed 18 ksi and that the decrease in length of the block should be at most 0.12% of its original length.
