· When the material loading is
in a cantilever mode, the criteria for material selection change. · Optimum stiffness now scales as (E /ρ2)and materials
with the maximum value of this quantity should be selected. · Optimum strength scales as (σy2/3/ ρ), a maximum value of this quantity being looked
for.
