Where to Find the Coefficient of Friction Between Paper and Plexiglass?

AI Thread Summary
The discussion centers on finding the coefficient of friction between paper and plexiglass, with users suggesting methods for testing it if no data is available. One effective approach involves using an inclined plane to determine the angle at which the paper begins to slide, which correlates to the coefficient of static friction. Users recommend experimenting with different weights to verify that the angle remains consistent, indicating a stable coefficient. One participant successfully calculated a coefficient of 0.35088, corresponding to an angle of approximately 19.33 degrees, achieved using a precise protractor. Overall, the thread emphasizes practical testing methods for determining friction coefficients when specific data is lacking.

I've searched for this on google, but haven't found anything; does anyone know where to find the coefficient of friction between paper and plexiglass?

If you can't find it, you can test it yourself. There are probably many different methods of doing so, you can probably find some online. The easiest would require a spring scale but if you don't have one you can find another method.
 
I don't have a spring scale, but do you have a suggestion on where to look for an alternate method? Thanks.
 
Put it on an incline and tilt it till it slides, but I suspect you're going to have a whole bunch of electrostatic stickiness.

that's a really good idea. at least to get the coefficient of static friction.

i would suggest trying it with a few different weights on top of the paper, but if the coefficient of static friction remains constant, the angle of tilt (when sliding begins) should be the same, no matter what the weight is. the coefficient of static friction is a function of the angle of tilt.
 
Thanks a lot guys. I did it by using the incline idea.
 
what did you get?

May I ask how you got it to that precision with an inclined plane?

No kidding, that's like 19.3349 degrees!

you just need a really good protractor. :smile:

well, i don't want to round yet because i need that to do calculations.

jeez
