Rotation About a Fixed Axis Model Description

This Java model will enable you to study the angular momentum that occurs in an experiment involving a rectangular box and a rotating axle. The fixed axis is in the z-direction. Users can tilt the box relative to the axle and can change the box dimensions. The simulation shows that the angular momentum vector L is not aligned with the the angular velocity vector unless the box is rotating about an axis parallel to a box edge. The simulation also shows the torque N that must be applied to the axle to maintain its fixed orientation. Additional windows display the frame-dependent tensor algebra in an inertial reference frame fixed in space and in a non-inertial reference frame attached to the rotating box with a rotation axis parallel to a box edge.
