I see. So it would look something like this: -------- | Mass | -------- ======= Sheet one --------- Sheet two

I have tested the books with a pulley and the rope would work with it. For the COF of paper, let's say that I have 2 A4 paper sheets. What would be the known mass? The mass of the paper above it? How would I determine the force required to separate them? Would I pull very gently?

Thanks for the tips, Curve Shifter. I have to give in a plan of what equipment I need by Tuesday, and then I can do some testing, as the experiment is going to be conducted in about one month's time. Before and after the final tests I will do some equipment testing and I will post some pictures...

I got the COF from the attachment, which it assumed to be 1. We are being judged upon our creativity, and originality of the experiment, as well as the actual science facts of the experiment and correct methodology. I will be using books with less pages as I want to achieve the point at which...

The assumed COF of paper is 1. I do agree that there is some force from the spine of the book; I have tried pulling normal exercise books, were the pages are stapled in place, and the binding did tear off; but only the binding of the spine. In order to have the books in a horizontal position...

Because for the experiment, I will hang (vertically) the two books onto a pole and attach different masses, and trying to find the point at which the books will separate. What would be the formula for the force now? EDIT: Or could I use pulleys to keep the books in a horizontal position like...

I see. I do have a question about the different sizes of paper (area). If it was A5, instead of A4, how would that affect the friction force?

So let's say I have only 4 pages, each with the mass of 2grams. ========== 0 grams of force ------------- 2 grams of force ========== 4 grams of force ------------- 6 grams of force The top one will not have any force acting upon it. The second sheet from the top will have 2 grams of force...

Hello all, I am working on a science project based upon paper, and I have chosen the affect of friction between two interlaced books. The attachment below is something I have found on the internet, as part of my research. I don't understand why the Rav = 0.5 * (mass1 + mass2) *9.81. Why is...
