Friday afternoon puzzler

[Chassis 33]

Afternoon folks, a bit of a puzzler for you. I need to find the COG of a car, its easy to find it in plan using cornerweightys, but how so i find the height of the COG. I could lift one side until it balances on edge at which point the COG will be above the contact axis and figure it out from there however I dont really have the hoisting equipment to do this, not even in a very Heath Robinson fashion.

Any other ideas?
Regards
Iain

If you can tilt the car fore to aft the change in weight distribution between front and rear wheels should enable you to calculate the height of the COG. Cant be arsed actually deriving the formula though.

5(1-(1-0.2t + 0.08t + 0.0016)
5(1-1+ 0.2t - 0.08t + 0.0016)
5(0.2t - 0.08t + 0.0016)
5(0.2t - 0.0816)
= t - 0.408t

im pretty sure is was mass per sq/m and something to do with weight/ height

allthough i could be very wrong
