[Unified-mailman] Foam Densities/Young's Modulus

[Charles P Coleman]

Class-

Foam densities as reported by Chris Graff on Wed 27-Feb-2002:

White foam: 15.0838 kg/m^3
Blue foam: 26.5573 kg/m^3

Be careful! Measured samples in 2002 showed significant variation in
density. In other words, measure your own! (2004 foam may not be 2002
foam...)

I don't have  Young's modulus information in my old e-mails. However, Prof
Drela has proposed a short experiment to measure it. I will share the
experiment with those who are interested.
