A tool steel cylindrical specimen, 6 in. long and 0.25 in. in diameter, is kept rotating like a cantilever beam and must be designed in such a way that rupture never occurs. Assuming that the maximum tensile and compressive stresses are equal, determine the maximum load that can be applied at the end of the life (see figure)
