Question details

Exercise 9.1/ A cow femoral compact bone is cut into 1x1x1 cm3 and tested. Assume the collagen fibers are all aligned in the z-axis, which is the femoral longitudinal direction the the cow femur. Youngs Stress max. (MPa) 0.31 0.30 Volume density Material 3 modules (g/cm3) 2.2 1.0 MPal 300 50 Mineral 60 Collagen 40 a- Which direction is the stiffest? b- In what direction the bone will be stretched the most? c- What is the density of the bone? d- Calculate the Youngs modulus in z-axis directions e- Calculate the strain in the z-direction due to the applied load of 10ON
