Torque and Shear Forces
The effects of torque and shearing forces can be demonstrated when
the matter model is constructed in a 5 x 3 x 2 configuration. In
addition, when supported only on one side a cantilever can be modeled
effectively.
Wave Patterns
By connecting many atoms (without nuts) in a linear arrangement with
the heavy springs, students can easily generate standing wave patterns.
The atoms should be laid on a smooth tabletop or floor for this activity.
The mass of each atom can be changed by inserting the included nuts.
