Calculate the impacts on size (diameter) and mass/unit length of replacing a natural bone in the leg with one made of steel, aluminum, or titanium. Use compressive strengths and densities provided in class for bone, steel, and aluminum. Use r=0.00443 kg/cm3, and s=848 MPa for titanium. Assume the bone is hollow with outside diameter 2.5 cm and inside diameter 3 cm. Maintain the same inside diameter. HINT: first calculate the load on the bone..
Explain the damage occurs for composite material with different expansion coefficients.
(a) Why most prosthetic limbs do not flex at the
ankle, but the ones designed for athletes do?
(b) Why is there almost no single test for
biocompatibility?
(c) Why is titanium such a commonly used
biomaterial?
(d) Why are most biomaterials not reused or
recycled?
