Hmmm. This isn\"t going to be an easy answerbecause 2 things have the right to vary a lot:1. Thestructure the the bone2. The direction of theforceBones are made up mostly of proteinand minerals (calcium and also others). Once we\"reborn, there\"s very tiny mineral. Our bones aresoft, versatile cartilage. This bones don\"t breakvery easily because they bending so well. Castle don\"tallow friend to be very solid though, because theforce of her muscles just causes bone bendinginstead the moving every little thing you\"re trying come move. (To see what mineral-free bones room like, placed awishbone in vinegar because that a while.) So to getstrong, us need an ext rigid bones. The rigidityalso renders bones much easier to break. If we usage ourmuscles, our bones get stronger too. They arealways being broken down and collected a little ata time. Together we get older, we shed bone mass,particularly if we don\"t get sufficient calcium or wesmoke or drink. This renders bones really brittlebecause we absence both functional cartilage and also sturdybone. Men likewise have denser skeletal than women ofthe exact same size.The direction the the forcemakes a distinction too. Uncover a bone picture ormodel and look at the lengthy bones that the eight andlegs. An alert that they\"re no straight? thebends and shapes make bones far better able come takethe anxiety that they generally are subjected to. They space often an extremely resistant to pressure in onedirection, yet vulnerable come it inanother.Want come see how the damage for agiven force varies through the direction? obtain smallwooden dowels that the exact same dimension and also subjectthem to the same force applied in various ways(for example, fall the very same weight top top the end ofone dowel and the center of another). Use eyeprotection and other security measures.Wantto see pictures of a fracture, a weird kind ofsplint, and healing bone? walk to: execute NOTgot to this website if you\"re quickly grossed out!

Answer 2:

Materials space often identified by the ultimatestrength i beg your pardon is the anxiety or push requiredto reason fracture or breakage.This stress can becaused by compression, tension, or shear. Theanswer because that the stamin of bone can probably befound in any type of physics textbook (it\"s a prettypopular subject). One number I uncovered for tensilestrength is 130 X 10^6 newtons per square meter. This could be in unfamiliar systems though. What isthis value in regards to psi or atmospheres?

Answer 3:

That counts on the bone.

The is really easy tofracture a little bone, specifically if the pressureis applied across the weakest point. I\"m not sureexactly how much press is needed, yet I cantell you the as tiny as 25 pounds of pressureapplied to among your tiny bones will cause afracture.
