A Friction Driven Oscillator
|
|
| |
A friction driven oscillator: A solid bar
is supported by two wheels that move in opposite directions. The resulting
movement of the bar is the difference between two friction transverse forces.
The resultant confines the bar roughly to the middle of the system. |
|
| |
 |
A video camera detects the edge of the solid bar.
The position of the edge is detected and recorded. |
|
|
| |
| A view of the friction experiment from above: A pancake
motor in the middle powers the two wheels through a set of gears and speed
reducers. The speed of the motor can be adjusted using the controller at
the left-bottom corner. |

 |
A side view of the experiment: Two red wheels drive
the bar's movement back and forth. Data on this experiment will be posted
in our preprints under "friction driven oscillator". |
