$16.(4$ points$)$ The $\backslash (\backslash$mathrm$\{$S$\}/\backslash$mathrm$\{$N$\}\backslash )$ curves below are for human bone loaded in compression $($C$),$ tension $($T$),$ and shear $($ S $).$ From these curves, we can infer that

a$.$ Bone is strongest in compression, less strong in tension, and weakest in shear $($if curves are extrapolated to $\backslash (10^\{\backslash$circ$\}\backslash )$ or $1$ cycle$).$

b$.$ A bone repetitively loaded to $80$ MPa in tension is unlikely to survive $\backslash (10^\{5\}\backslash$mathrm$\{$cycles$\}\backslash )$ before failing.

c$.$ Bone is more susceptible to fatiguing in compression than in shear. $($c$.)$ All of the above.
