PURPOSE: To demonstrate torsional SHM, and to quantitatively show the effect of moment of inertia on the period.
DESCRIPTION: Various combinations of masses and moments of inertia can be placed on the platform to study the effect of changing the moment of inertia on the period of rotational SHM. This one is adequate for quantitative measurements.
REFERENCES: (PIRA 3A10.30) For a qualitative version see G1-41: TORSIONAL PENDULUM.
EQUIPMENT: Torsional pendulum with additional masses.
SETUP TIME: None.
