diagram for demo

Torsional Wave Model. Light-weight rods are mounted, in a parallel fashion, on a long piece of spring-steel wire. An electric motor can be used to introduce a periodic oscillation to one rod, and a transverse wave travels down the length of the apparatus. The opposite end can be free or tied down, -or connected to a dash-pot assembly for damping, -or connected to another model of same or different dimensions
