Moments of inertia and torsional vibrations with CobraSMARTsense

Article no: P2133167

Principle

The moment of inertia of a solid body depends on its mass distribution and the axis of rotation. Steiner's theorem elucidates this relationship.

Benefits

Angular oscillation apparaturs includes five different body shapes for in-depth experimenting
High-precision movement sensor
Very robust and durable setup

Tasks

The moments of inertia of different bodies are determined by oscillation measurements.
Steiner's theorem is verified.

Learning objectives

Rigid body
Moment of inertia
Centre of gravity
Axis of rotation
Torsional vibration
Spring constant
Angular restoring force
