Questions
1. From your results, what mathematical relationship must there be between

1
and

2
in order for the beam to be
balanced?
2. What torque is exerted on the balance beam by the upward pull of the pivot point?
Extension
If you have time, try adding a third Protractor and Mass Hanger to the beam on the same side of the beam as the
second Protractor.
