Armor Attack


 Model Description This training aid demonstrates a practical application of the kinematic relationships for a translating and rotating frame of reference. This demonstration should take 10-15 minutes. Engineering Principle This lesson is an application of the previously developed vector equations for velocity and acceleration in a translating and rotating frame of reference. Required Items Item […]

A Day at the Races: Moment of Inertia


 Overview This is a demonstration of the basic principles underlying the behavior of rotating bodies. A cylinder “race” is used to show that the closer the mass of an object is concentrated to an axis of rotation, the faster it will spin because it has a lower moment of inertia, which is a measure of […]
