Answer following questions:
a) Explain the difference between an isotropic material and ananisotropic material. Give one example of abiological materialother than bone that is anisotropic and explain how it isanisotropic.
b) It is well documented that humans are typically taller firstthing in the morning, but get progressively shorter (by very smallamounts) as the day goes on. Based on what you know about theviscoelastic properties of human body tissues, can you explain thisphenomenon?
c) Explain how the creep response of a viscoelastic material isdifferent than the stress-relaxation response of that material.Provide an example of one biological material for which creep is asignificant issue to deal with and one biological material forwhich stress-relaxation is a significant issue to deal with.

a Materials are considered to be isotropic if the propertiesare not dependent on the direction whileAnisotropic refers to theproperties of a material that is dependent on the directionAnother condition that can fit the anisotropic definition is thepresence of different properties in different directionsCartilage is an anisotropic material The anisotropy results inpart from the structural variations that are Interactions takeplace among the fl uid proteoglycan molecules and variouselectrostatic charges providing superior quality of lubricationand shock absorption The cartilaginous tissue is extremely See Answer
