I'm working on a project where it would be helpful to know the temperature forces on an existing bridge pier. The bridge bearings consist of pots with a stainless steel plate sliding on Teflon with a center guide bar. The bridge was built in the mid 80's. The stainless steel surface appears to be clean.
What I would like to know is what the coefficient of static friction is for this bearing.
0.04 is a commonly given value for stainless on Teflon. However, I wonder what it might be in practice after 25 years of wear.
Thanks,
JMH
