Assume that Young's modulus for bone is 1.5x10^10 N/m2 and that a
bone will fracture if more than 1.5x10^8 N/m2 is exerted. (a) What is the
maximum force that can be exerted on the femur bone in the leg if it has a
minimum effective diameter of 2.50 cm? (b) If a force of this magnitude is
applied compressively, by how much does the 25.0-cm-long-bone shorten?
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..
Besides using strain gauges, name and describe two
alternative ways of measuring strains or deformations. List two
benefits of using each strain measuring system, compared to
strain gauges.

- The rapture strength of bone tissue is 100 MPa and Young’s modulus is 10 GPa. Calculatevalue of longitudinal strain bone at which the fracture of the bone occurs.arrow_forwardChanges in cortical bone density and bone geometry occur with aging in both men and women (Table 1 from Russo 2003). These changes manifest as decreased bone strength, which has the clinical impact of increasing the risk of fracture with increasing age. However, elderly men are much less prone to fracture than elderly women. It has been suggested that age-related bone loss is the consequence of endosteal bone resorption resulting in changes in bone geometry (~2mm less cortical bone thickness in women as they age) and contributing to relative differences in fracture risk between men and women. Cortical bone area decreases in women between the ages of 20 and 85, whereas there is no significant change in cortical bone area for men over the same age range (Table 1).
