increasing and decreasing the hanging weights, the strain should be the same for the same stress. That is the Young’s Modulus should be the same for both cases. Did you observe this? We did not observe the exact same Young’s Modulus but we were extremely close. Both cases were about 0.2 different from eachother. 2. In your plot, how well do the data points fall in a straight line? What would be the factors that causethe deviations from a straight line? 3. If the wire in your apparatus is replaced with one twice as thick, which of the following would change when you add the first kilogram, and how: ΔL, F, stress, strain, and value of Young’s Modulus. Give quantitative answers to the charges, for example, the new value would be twice as large as the old one. If the wire was twice as thick, ΔL, stress and strain would change once the first kilogram was added. ΔL would be half the value, F would be the same, stress and strain would also be half the value.
