A vehicle with the mass 190kg, wheelbase 1,56m and tyre static radius 222mm is weighed. Scales measure 83kg (front) and 107kg (rear) when the car measured on the perfectly flat ground and the same values when the front axle is elevated by 0,85m. What is the car’s COG height? Give answer to the nearest whole number in mm

draw all forces working on car and create balanced equation.
Fb‘ * L*cosθ – Fg * |AC| = 0 (rotated around point at A)
|AC| = |AB| + |BC| = (h – r) * sinθ + a * cosθ
a = L * (Fb/Fg)
Final formula: h = (Fb‘- Fb)/Fg × L × cot(θ) + r

Fb‘ = m*g (at rear axle while front tyres are lifted)

Fb = m*g (at rear axle while car standing on ground)

Fg = m*g (at COG)

L = wheel base

sin(θ) = H/L

r= radius of tyre
