Torque Experiments (continued)
2.
Wrap a rope or string around the groove of the upper platform (see
Figure 7).
3.
Attach a Force Sensor to the rope.
4.
Ask one student to sit on the stool.
5.
Ask another student to pull the rope to accelerate the rider. Be
certain to pull the rope tangent to the platform.
6.
Repeat step 5 two more times, increasing the amount of force
(torque) in each case. A graph with torque on the vertical axis and
angular acceleration on the horizontal axis will produce a slope
equal to the moment of inertia for the system.
7.
The experiment could then be repeated with the mass of the system
distributed in a different fashion. For instance, the student could be
tucked in while rotating on the platform in the first experiment and
have arms extended in the second experiment.
