Victoria Wood PHYS 221 – Section 1 Experiment #9: Torque and Rotational Motion Partner: Shamsa
Results In this experiment, we were able to measure the torque on a rigid object and determine the conditions necessary for static equilibrium to occur. By balancing the meter stick and hanging masses on each end, we were able to evaluate torque and determine uncertainties.
