SDOF Drop Shock Online Calculator with Animation

This is the same drop shock calculator given in the 4/28/2014 posting.  However, via javascript an animation feature has been added.  Simply click the button to view the drop.  This should work in all browsers except for IE 8 and earlier.

If the calculator has not been run for a few minutes the animation may not execute.  To do so simply refresh the page.

A limited number of time steps are used in the solution.  For large drop heights, low damping and stiff springs the drop response will be multiple low damped bounces and the animation will likely stop during a mid bounce.  For smaller drop heights, moderate to high damping (>10%) and soft springs (fn < 10-20 Hz) the drop response will be one to a few rebounds and the animation will likely stop at the static deflection of W/k.
