A Doubly Suspended Pendulum

Home \ experiment
Student Manual

The objective of this experiment is to determine the moment of inertia of a bi lar pendulum experimentally and then comparing it to the theoretical prediction. The investigation of the bi lar pendulum includes determining the accuracy of the moment of inertia inferred from the experiment and understanding the underlying experimental process.

Sample Results A graph showing relationship between time period and inverse of D (distance between the two filars)
Experiment Code 1.19
Version Oct 23, 2019
