Experiment: Ruler Bending at Different Points

[inutard]

Hello guys. I was doing an experiment on how much a ruler bends at different points when a mass is hung from it. In the experiment, one end is fixed to the table and a mass is hung from the ruler at different points. The relationship seems to resemble a logarithmic curve. Any explanations for this?
