2. Let's look at the femur – the largest, longest, and strongest bone of the human skeleton. Let's do some calculation to see if it makes sense. How much does the femur shorten when you stand on one foot? (With no stress the femur is about 0.5 m long. The cross-sections effective area is approximately 370 mm2.) would happen if you try to lift a truck? The femur is probably going to break. Femur is considered a stiff 3. ultimate strength X fracture yield but fragile material; the bone will break under a large E enough force. The linear relationship (Hooke's law) only applies for an elastic region. Beyond this the material post-yield strain will begin to yield and eventually fracture. Strain 4. Assume the bone will fracture if more than 1.5 x 108 N/m2 is exerted. What is the maximum force that can be exerted on the femur bone? Stress
