APPARATUS
crystal model
202-16-F-1
DESCRIPTION
The crystal model consists of an array of balls and springs. It can be rearranged into 1- and 2-D configurations.
There are 40 balls, 60 heavy springs, 60 light springs, 40 nuts to add to mass of balls.
The 1-dimensional arrangement can be used to show transverse waves or, with the brass rod through their centers, longitudinal waves.
The crystal model can be used to show normal force, torsion, shear stress.
