Ablock of 250-mm length and 54 × 40-mm cross section is to support a centric compressive load p. the material to be used is a bronze for which e = 95 gpa. determine the largest load that can be applied, knowing that the normal stress must not exceed 80 mpa and that the decrease in length of the block should be at most 0.12% of its original length.
