Rotation<br />
Physical Pendula<br />
This set of six objects is perfect for studying Physical<br />
Pendula, Moments of Inertia, and the Parallel Axis<br />
Theorem. Each piece fastens directly to a Rotary Motion<br />
Sensor to measure the objects acceleration due to an<br />
applied torque, or the period when the pendulum freely<br />
oscillates.<br />
Each piece is made from 1/4 inch thick aluminum plate.<br />
Apply a known torque and measure the angular acceleration<br />
to calculate the moment of inertia of the object.<br />
Multiple holes in the plate allow investigation of the<br />
Parallel Axis Theorem.<br />

Center.of.Mass.<br />
The Pendulum Bar has holes spaced<br />
at 2 cm intervals. A graph of<br />
oscillation period vs. pivot hole<br />
position shows that there is a<br />
unique placement that gives a<br />
minimum period. This location<br />
can be verified using calculus.<br />
Moments of Inertia<br />
Add the Mini-Rotational Accessory to the Rotary Motion Sensor<br />
(pages 2 and 5) to study Moments of Inertia of an aluminum<br />
disk, a steel ring and a metal rod. Additional experiments<br />
can be performed using the same apparatus: The period of a<br />
physical pendulum and conservation of angular momentum<br />
when a ring is dropped on a rotating disk.<br />
Includes<br />

Clamp-On Super Pulley<br />
Unique design allows pivot<br />
exactly at the edge. Measure<br />
the period of the thick ring<br />
oscillating at either the inner<br />
or outer radius.<br />
