a) Using the stress-strain graph below, explain which polymer (A or B) has the higher Youngs Modulus. What does this mean about the relative properties of polymers A and B? AX A' X stress strain b) The A and A' curves above are both true for the same polymer! How can this be true, and what does it tell you about polymer "A"? c) Polymer "B" can handle a lot of strain, but prior to the break point (X), the...
