A torsion pendulum is the horizontal twisting of some suspeneded "bob" first to one side, then the other, as it hangs from a vertical support. Review the Torsion Pendulum Experiment at the University of Toronto to see some of the factors involved.
Our goal in this experiement is to come up with a formula for the behavior of the pendulum. As we vary the length of the pendulum, does the period vary directly? inversely? by some power -- the square or square root? If we vary the mass of the rod, or its thickness, how does the period change?
You will need to duplicate to some extent the apparatus shown in the University of Toronto summary.
Your report should include a description of your equipment and methods, your data table, and your determination of the factors on which the period of the torsion pendulum depends.
