If record 3 corresponds to the end of the linearly elastic region and record 5 corresponds to fracture point, carry out the following:
a. Draw the tensile stress-strain diagram for the bone specimen. (5 marks)
b. Calculate the elastic modulus, E, of the bone specimen. (2 marks)
c. What is the ultimate strength of the bone specimen? (1 marks)
d. What is the yield strength of the bone specimen? (1 marks)
e. What is the fracture's strain of the bone specimen? (1 marks)
Figure beside illustrates a bone specimen with a circular cross-section.Two
sections. A and B.that are Lo =6 mm distance apart are marked on the
