A compressive force of 4 x 104 N is exerted at the end of a bone of length 30cm and 4 2 square cross-sectional area. Compressive strength of bone is 7.7 x1010 N/2 and Youngs modulus of bone is 1.5 x1010 N/2 . a. What is the relationship between Stiffness (or Youngs modulus), Stress and Strain (i.e. what is the formula)? b. What is the relationship between Stress, Force and Area (i.e. what is the formula)? c. What is the relationship between Strain, Change in Length and Original Length? d. Express Strain in terms of Stress and Youngs modulus e. What is the strain in the bone? f. Express the change in length in terms of the original length and strain g. What is the change in the length of the bone? h. What is the new length of the bone
