Your work on rubber band calibration has been received. Scroll down through the document to see any comments I might have inserted, and my final comment at the end.
I hope this is satisfactory results.
Also, the lack of what you would like to call this?
Rubber Band Exp1 will be fine.
also, on the fifth graph you said,
Reading the point on the y axis as F = 2.6 or maybe F = 2.7 we see that the curve gives us a force between 2.6 and 2.7 Newtons
this appears to me as 1.6 or 1.7, am I missunderstanding?

I recorded, on a double reduced ruler, the difference between 28.7 and 10 (18.7) and then compared it to a centimeter ruler. it was marked by 1 dash, .02
I used a digital camera to photo the measuring device while I held it up against the rubber band. This eliminated the error of accidently moving the measuring device while trying to read it.

Your work on this experiment will be compiled and you will receive a more extensive analysis and a reply after the due date. On first viewing the results you have submitted appear to be good.
I like the idea of using the digital camera. Not everyone has one with good resolution, but for those who do this can be very handy and can as you note improve accuracy. Also less cumbersome, as you also note, and very likely quicker.
