I wish to propose a metric: tensile strength as a function of density, call
it specific strength. Strangely enough, the units come out to the square
of velocity, m^2/sec^2:
pa/{kg/m^3}={N/m^2}/{kg/m^3=Nm/kg=kg*m^2/kg*sec^2=m^2/sec^2
Nowthen, we want to make a table of specific strengths* of various
materials in terms of m^2/sec^2. Question: has anybody heard of
such a technique before? I cant find it in any of my materials science
texts, but it seems obviously useful for topics like the space cable and
such. Doug? Anybody?
* strengths: theres a world with 9 letters and only 1 vowel. Is that the
only word like that? spike
