Purpose
To illustrate the concepts of torque and levers.
Parts
- The lever paradox may be found fully-assembled on shelf C3
- A balance scale using the principle illustrated by the lever paradox is also found fully-assembled on shelf C3
Setup
No setup necessary. Move weights on arms of lever paradox and note that it stays balanced regardless of the weights’ positions.
This concept is implemented in the design of the balance scale: objects do not have to be placed directly in the center of the plates to be weighed.
