Document Summary

Bsci 207, dr. bretton kent - monday, november 26, 2018. Motility- transfer forces from one region of an organism to another or to the external environment. Know stress(force per area that results from strain) -strain(change in length) diagram (slide 7) Extensibility- strain prior to deformation(amount it"ll move when hit) Elastic region- place where material immediately recovers (rubber band goes back perfectly) (skeletons mostly operate here) Viscoelastic material- delayed deformation due to internal friction- dissipates force (most biological materials) Composite material- tension-resistant material with compression-resistant material (skeletons) Plastic region- slight deformation (stretched out rubber band) Localized properties- occur when load is predictable in direction.
