9 A copper rod was placed under tensile stress and the tensile strain in the rod was measured. The graph shows how the tensile stress required to cause a tensile strain in the rod depends upon the tensile strain. Tensile stress X Tensile strain What does point X represent? X A the fracture point of the rod B the limit of proportionality for copper X C the maximum tensile stress in the rod X D the yield point of copper
