[b]Friction Coefficients[/b]

[ariky]

Hello Everybody,
I am looking for data about static/dynamic coefficients of friction between rubber and steel (low-carbon) for dry and for [COLOR=red yellow]oily[/color] conditions.
Untill now I was able to find very little information.
I'll appriciate if you could either direct me to any web-site that contain this info or post the relevant pages.
Regards,
Ariky

Rather than rely on handbook values you should test your specific application.

Friction is pretty easy to test provided you have access to the materials of interest and gravity.

 

[FACS]

I think running an inclined plane experiement for each material would give you the coefficient; it's easy enough.

To compare to.

Questions like this usually arise from a specific problem.

When you just get an answer from a book you usually have no idea of the nature of the test conditions that gave rise to the answer.

Rather than look for an answer in a book it's my experience that it is better to conduct your own test simulating the problem. In this way you gain a better understanding.

Good luck.
