Unformatted text preview: Quiz 6 for ChB 350 Fall 2009 Name: Ke i 1. Below is a table listing the mechanical properties of bone. (a) Plot the stress—strain curves for the bone of a 20—30 year old and a 60—70 year old. (make
sure you label your axes and provide units for the quantities) 8.9 6—?‘\ (b) What is the elastic modulus of bone (provide for the 20-30 year 01d)? (0) How much tougher are the bones of the 20-30 yr old? (give a percentage) 5‘19?) " (d) On the same plot, sketch the stress-strain curve for ararnid ﬁber reinforced epoxy. (It is a
brittle material with a tensile strength of 1.38 GPa and a percent elongation of 1.8%). 7..
