No, I have not. I'm interested in particular with what seems to be lubricated friction. Specifically motor oils. I was thinking about lubricating a surface and performing the standard inclined plane test to see which one causes the object to move at the smallest angle?
Dos this make sense or...
I want to test several different fluids on an inclined planes and figure out which one is the most slippery. What would be the most scientifically sound way to measure this?
