A hollowed long bone is under axial loading (uniform) of 2000 N. The marrow cavity is assumed uniform of 15 mm in diameter (figure). The outer diameters are changed from 20 mm to 30 mm. Assuming E=18GPa, and v=0.30, find σ xx ,ε xx, at x=0,x=L/2, and x=L. Find the total deformation, δ(x).L=500 mm. The implant and the bone are connected with same δ. (40 pts)
