I've beat up the units issue so I don't think that's the problem. The system is pretty simple and I've been staring at it for a couple of hours so it didn't occur to me to give more detail... Essentially, I'm looking at a spring to ground with K=238.1 #/in. A weight (W) of 7.43# is being...
This is a simple(?) problem but my ability to perform basic calculus disappeared long ago. I am working thru the equations for a spring response to a dropped weight. My primary reference is Shigley (for just about everything!) and I've validated the eqn's for deflection and max force. However...
