Use the setup shown below to measure how much two different materials deflect and how the length of the cantilever beam affects the deflection.
Do 5 measurements of different lengths for each material.
Use a spreadsheet to calculate the theoretical deflections. and compare these results (% error).
What are some areas where uncertainty would contribute to a variation in the results?
