I've been thinking about this for a long time. I would like to be able to quantitatively evaluate chassis stiffness. I have some ideas for increasing stiffness, but I'd like to be able to measure those changes by something other than the seat of my pants ("It feels stiffer.").
My best idea so far is to place a car on three jack stands of equal height and measure the droop of the fourth corner. Any other ideas? Any physicists that can help out here? |
