>MATERIAL; TENSILE STRENGTH; MOD. OF ELASTICITY; DENSITY

>UHMW; 4.75 KSI; 90 KSI; 0.034
>HDPE; 4.6 KSI; 170 KSI; 0.034
>6061-T6 ALUMINUM; 45 KSI; 10,000 KSI; 0.098
>1018 Cold Drawn STEEL; 64 KSI; 30,000 KSI; 0.283

Hmmm, something is wrong with those density numbers. If they were correct,
steel would be lighter than balsa wood.
