## The Forces in Bone Carvingby Drew Marien

I did A presentation on the forces to make different bone carvings I will compare the force of friction on a bone necklaces that is polished and a none polished necklaces. Then I will do a conceptional peace on my jewelers saw and my dermal tool. That is what this presentation is what will be made up of.

The first calculation I did for one of my polished finished bone pieces. I fingered out the how many newtons it has as it is static which is .14N then i started testing it. i added a 50 gram weight and a 100 gram weight and found the mew for the 50 gram and the piece was .54 mews and for the piece and the 100 gram it was .56 mews for an average of .55 mews

next I calculated the force of friction for an unfinished piece of bone.I fingered out the how many newtons it has as it is static which is .14N then i started testing it. i added a 50 gram weight and a 100 gram weight and found the mew for the 50 gram and the piece was .7 mews and for the piece and the 100 gram it was .71 mews for an average of .705 mews

next is my conceptional on the forces of a jewelers saw. so I guest that that since the blade was slicing through the bone with so much ease it had a vary small coefficient of friction and my guest was based off the small teeth on the saw since it was uneven it was highting the high and low points of the saw causing it to have a small coefficient of friction

last but serenely not least is my main power house behind carving my dermal tool. This was the hardest to come up with a theory because it moves at such a high rate of RPM. but my guess is as good as your but I was going off of its acceleration at speeds from 0 to 5,000 RPM in fracton of seconds and with such a high acceleration it can cut through anything with the matter of small blades called bits to help do the cutting
