During benchmarking cars of the previous year engineer “A” sees how big the differences are concerning the pitch angles. He wonders how much acceleration is necessary, before the car’s front axle starts lifting. He does a rough calculation with the equation below and assumes on one hand a stiff car (no wheel travel through deflection) and on the other hand following vehicle data: m = 260kg; h_S=260mm; l_v=830mm; l=1570mm; g=9,81 m/s²
