A) Plot the stress distribution at the cross-sectional plane defined by points A and B. Label the neutral axis and which side is in tension or compression. Do not provide stress magnitudes.

B) If point A experiences strain of magnitude 91 μm/m, determine the magnitude of force F. (Recall: for this case, stress and strain are linearly related by one material constant.)

C) Assume the force F and cross-sectional area are unchanged from (b), but the bone cross section is now a circle rather than an annulus. Determine the new strain experienced at point A.
