![]() ![]() The previous owner was in over his head with it, he was not mechanically inclined and was going broke trying to get the work done. That’s a nice rig that just needed some TLC from someone with the ability to do the work. I thought that truck looked familiar, I did some work on it for the previous owner. just trying to illustrate whats happening with things that people can readily see and mentally picture deforming under the impact. (I was originally going to compare dropping something into Jell-O, which mimics the behavior of a shockwave propagating through a solid pretty graphically, but its pretty sticky so nothing would ever really bounce <_<, which kinda kills the visual)Īnd compare the source of the forces propelling the 'bearing' back up. (consider the hardness of the face similar to how taught the trampoline surface is, really really tight being very hard, really slack being very soft) Then think of dropping an underinflated water balloon (key being that it doesn't break) on a trampoline, balloon flattens briefly and returns to its original shape, dragging itself back up, trampoline sags minutely under the load and then returns to its original position, also forcing the balloon back up with it. Think of it like comparing what would happen if you were to hold a ruler on the edge of your desk, with say 6" hanging off and twang the tip (your finger would be the bearing analog here), lot of bend lot of return, lot of vibration (noise) (extreme exaggerations of scale here to illustrate principle) The heel is much thinner and will have a tendency to flex (extremely minutely) and rebound, whereas the rebound from the center is strictly coming from the elastic deflection of the face and material immediately beneath it and within the bearing or hammerhead doing the bouncing.
