The Oil Rig

 

 Model Description This training aid demonstrates the kinematics of multiple connected rigid bodies in translation, rotation, or general planar motion.  This demonstration should take 10-15 minutes. Engineering Principle This training aid demonstrates the kinematics of a multi-body structure.  Motion for each part of the structure is classified and discussed.  A KNEX motor brings the training […]

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 […]
