Part 1: 10 marks] Given the graph below which shows a plot of force versus total sample length in a tensile test of a polymer. The sample is cylindrical, with an initial diameter of 1 cm and an initial length of 10 cm. From the data below, calculate the following and show detailed calculations 1. The modulus, 2. yield stress, 3. yield strain, 4. tensile strength, 5. % elongation Force (N) 1200 Langh (cm)
