Coefficient of Kinetic Friction lab question

[jman1114]

Hey,

New here so I don't know if I'm posting this in the right area if I'm not please redirect me. I have this lab on static and kinetic coefficients of friction. One of the discussion questions is what are the expected or known values for wood against rubber and steel against wood. Basically the lab was drag a rubber stopper and a metal puck across a wooden board and then calculate the coefficient (I know easy). But I can't find the coefficient of kinetic friction for each of those two and I've looke at 20 or 30 websites. So my question is could someone either point me in the right direction or show me a website that has the values because I'll need it for referencing.

Thanks a lot for that link it really helped. But does any possibly off the top of their head know what rubber against wood might be?
