Learning Goal: To use the method of superposition to calculate a beam deflection and slope. For beams with small deflections, the assumptions for using the method of superposition apply: the deflections and slopes are linearly related to the load, and the deflections do not significantly change the original geometry of the beam. The deflections and slopes for beams subjected to multiple loads can then be found using linear combinations of known results for individual loads. Use the two loadings below and the principle of superposition to answer the following questions.
