How weight affects the amount a fixed dowel deflects.

... Planning The Experiment: How weight affects the amount a fixed dowel deflects. Labelled diagram of proposed set up: When reading off the ruler, it is necessary to crouch otherwise parallax will occur and readings will be inaccurate. Controlled variables: There are 4 independent variables in this experiment. The thickness of the dowel, the weight being hung from the dowel, the distance the weight is being hung from the dowel and the amount of over-hang of the dowel. These will produce a dependent variable, the bend/deflection of the dowel. I will use the weight being hung as my independent variable, and I will keep the others constant. Expected independent variable range: I will take readings between 0-5N (0-500g) inclusive. From zero, I will take down readings in 0.5N (50g) increments. Each reading will be taken down 3 times with a margin of error of 2mm either way and to 0 decimal places. Once all 3 readings have been noted,
