What factors affect the bending of bridges? Abstract: This experiment was designed and conducted to find out how different factors affect the amount of bending of the beam. The two variables that were tested were the amounts of weight and the position of the weight on the plank. Aim: To find out how weight and different placements of the weight affect the bending of the beam. Hypothesis: It is predicted that the wood will bend more if there is more weight on it. When the weight is positioned
