Please answer question 17:
The femur (the largest leg bone) of a certain person has a cross
sectional area of 3.57×10-4m2 and a length of
39 cm. If the compressional strength of bone is 104
MN/m2, what is the force required to fracture this
femur?
Correct, computer gets: 3.71E+04 N
17. [2pt]
In the previous problem, what is the elongation of the femur when
it is on the verge of breaking? Use positive values if the bone is
longer, and negative values if it is shorter.

The leg bone (femur) breaks under a compressive force of about 6.30 × 104 N for a human and 12.7 × 104 N for a horse. The human femur has a compressive strength of 160 MPa, whereas the horse femur has a compressive strength of 140 MPa. What is the effective cross-sectional area of the femur in a horse? (Note: Since the center of the femur contains bone marrow, which has essentially no compressive strength, the effective cross-sectional area is...

READING 2 Materials fracture when the force per unit area, called STRESS, exceeds a critical value. In general, the critical stress depends on the direction as well as the magnitude of the force. For example, bones break differently when subjected to torsional (twisting) stress than when subjected to compressional (or squeezing) stress. Let us consider compressional stress.
