[TheForge] FW: [The_Anvil] Dont put your tongue on a frozen anvil

[Grover Richardson]

Compressive strength of an anvil is different than twisting expanding
strength of metal.  I don't remember the specific names of such (too long
out of college<G>), but do remember the concepts.

Actually, there is a famous story about Liberty ships in WW2- several 
of them broke right in half in arctic waters, running supplies to 
Murmansk.
It turns out that the cold, along with the motion of the waves, caused 
them to change stucture enough that with the welding techniques they 
were using, the boats just fell apart.
As I remember, different welding techniques solved this problem- maybe 
someone knows the real story.
