Problem
1. If a baseball bat (thicker on one side than the other) is cut at the location where it balances, with both side be of equal weight?
2. Can the meter stick be balanced if a mass is attached on one side only?
3. In each of the procedures of this experiment, are the forces also balanced?
4. How do the different masses being balanced show the properties of a lever?
5. What are the sources of error in this experiment?
6. If the meter stick is replaced with a metal stick, and the whole experiment is done inside water (e.g. on the floor of a swimming pool), will the same principles apply as they do in ir? Will it matter if the masses are made of different materials (e.g. if the 200 g is made of iron or lead, or wood)?
7. Why does a tight rope walker carry a long, horizontal bar to keep him balanced?
