Here is the actual dynamic behavior of the undamped forced spring mass system. The following list shows the definitions of parameters and variables:
Experiments were conducted with one mass, one spring, one set of initial conditions, and six forcing frequencies. You can see the actual behavior of the undamped forced spring mass system depicted in the graphs.

A non-contact optical (infrared) sensor is used to measure
the position of the mass. Here is the plot of
