2. Bone is an anisotropic tissue that supports higher loads in the longitudinal direction, due to the high level of organization of collagen and hydroxyapatite. The elastic modulus of a femur was found to be 40 GPa when measured in the longitudinal direction, and can be modeled as a composite with continuous oriented fibers. The volume fraction of the hydroxyapatite inclusions is 50%. The moduli of the inclusions and matrix are 79 GPa and 1 GPa respectively. The femur has a radius of 3 cm. Determine the necessary radius of bone with entirely isotropic mechanical properties (i. e. inclusions are random particles now). In both cases, bone should not exceed a strain of 1%
