rowlem $2.$ The engineering stress$-$strain curve for a collagen fiber bundle from which a human tendon is composed is shown in the following diagram $(k$ si is psix ${10}^3).$ A segment of Achilles tendon has a length of $6\mathrm{.}5$ inch and an approximate cross$-$sectional area of $0\mathrm{.}230i{n}^2.$ The fiber bundle fully recovers to its original length when it is stretched up to a limiting strain of $0\mathrm{.}05i\frac{n}{i}n.$ Beyond that limiting strain, the fiber bundle does not fully recover and deformation is not fully elastic.

a$)$ determine the modulus of elasticity of the tendon $($IDT$/$In$$ or psi$)$

b$)$ fibers of the tendon tissue can be elongated up to a strain of $0\mathrm{.}05$ in$./$in$.$ Without a permeabet shape distrotion. Determine the modulus of resilence of the tendon. $($Psi$)$
