Day 5

As mentioned in the last post, today was mostly gathering data.  It is always interesting watch the different techniques for determining the period.  Some students are convinced they can accurately time one cycle.

SIDEBAR:  We have two different version of the inertia balance.  We have some smaller commercial ones (they are pretty old, so I’m not sure where they were ordered from) and some larger homemade ones.  I add some mass (taped to the bottom) to some of each type to vary the fundamental so all the groups do not get roughly the same slope value.
