Document Summary
Depending on the type of material, some things may deform more readily than others. Apply large enough force, eventually it will break. Your leg bone is 0. 3m long with a cross-sectional area of 4. 0x10-4m2. The force of compression when landing is 1. 5x103n. Imagine getting kicked in the back by a ninja, vertebrae shear across each other. The disc between two vertebrae has a height of 0. 20cm and the disc radius is 1. 0cm. 100n, and the g for cartilage is 2. 0x107n/m2. Elasticity: the ability of an object or material to return to its normal shape after being stretched or compressed. Tensile stress: the stress applied to a material is the force per unit area applied to the material. The maximum stress a material can stand before it breaks is called the breaking stress or the ultimate tensile stress. ( = f / a)
