This is a question for the engineering geeks here.

Say you were towing a little trailer behind your Vanagon. Say that the
trailer had a rudimentary suspension consisting only of leaf springs. Say
that this trailer also had tires, the pressure of which could be adjusted:
higher pressure results in a harsher ride, while lower pressure results in
a softer ride. Say you wanted to determine the optimum pressure of ride vs
tire squishiness but were unable to find a small boy to ride in that
trailer to report back about smoothness of ride v tire pressure while the
experiments were being conducted, so lacking that small boy, your thoughts
naturally turn to instrumentation. Okay, so say you had a laptop computer
(WinXP) which could ride in the passenger seat, and /three/ business days
in which to acquire the needed sensor (accelerometer?) as well as the
software to display the ride bounciness.

Could it be done?
