4) There is a difference if you measure the diameter and length of the wire with 1lb or 7lbs on the hook however, that difference is not hugely significant. Because the elongation of the wire within each pound is so small, it is not noticeable through the naked eye. The diameter is changing because with each addition of weight to the hook, the micrometer must be adjusted to make bridge level. The length is changing because elongation is occurring. Conclusion This laboratory was very informative and the objective was met. Our results prove that it was a success and everything turned out as it should have. The data points in both my graphs fall in a very straight line that when adding the tool of straight lines in Excel, it is almost impossible to notice proving that all the points fall within the desired category. Young’s Modulus of elasticity was determined through the calculation of the slope for both graphs. The slope in Graph II was negative as should be because the weights were exponentially decreased. I learned that even though you cannot see through the naked eye that elongation is occurring, it is with more weight added.
