Repeat Prob. 2–28, except that the design situation is failure by excessive deflection and it is desired to minimize the weight.
Repeat Prob. 2–28, Consider a cantilever beam that is loaded with a transverse force at its tip. The following materials are being considered: tungsten carbide, high-carbon heat-treated steel, polycarbonate polymer, aluminum alloy. Using the Ashby charts, recommend one or two of the materials for a design situation in which failure is by exceeding the strength of the material and it is desired to minimize the weight.
