Document Summary

Lecture 8 - review questions for midterm 1. The area of the bone determines the amount the bone can hold. It"s the cross sectional area that gets the force. Skeletons of large animals more fragile than skeletons of small animals. Strength of the bone is determined by sa, so that needs to increase. Small is easier to run, smaller forces on the bones. The force that bones take on depends on the mass of the organism. Stress is amount of force put on to make the change. How much force to get it to change shape. Usually they go into a zone of plastic response. First it"s elastic --> will return to original shape. Often after the plastic zone, already starting to break --> just a bit more energy to really break it. How much you can deform before it snaps. More load (more force per area) --> more deformation.
