Friction Coefficients 1

[PST09]

Gents,

I was just wondering your opinions/any good refrence material you know of on the friction co-efficients of some of the following:

Steel - PTFE
Steel - Concrete (Wet or underground)
Steel - Conrrete (dry)

I have had a look around the net and found a few bits but nothing conclusive.

Thanks in advance!

PST

So it seems with teflon under .1 and much lower and steel-concrete no less than .45 just in case.
