1Q10.75 - Parallel Axis Wheels
![]() |
|
Code Number: 1Q10.75
Demo Title: Parallel Axis Wheels
Condition: Good
Principle: Parallel Axis Theorem
Area of Study: Mechanics
Equipment:
Pasco Rotational System and Hanging Weights.
Procedure:
Place the large wheel at the desired radius on the rotational support arm. Note that the wheel can be mounted so that it does not turn as the support arm is rotating, or by turning it upside down it can be spun on its own axis as the support arm is rotated. Leveling of the apparatus will be required. When the hanging masses are allowed to fall the rotational inertia can be calculated.
