Example - Car Crash. A car with a mass of 2000 kg drives with speed 60 km/h (16.7 m/s) before it crashes into a massive concrete wall. The front of the car impacts 0.5 m (the deformation distance). The impact force can be calculated as. F max = 1/2 (2000 kg) (16.7 m/s) 2 / (0.5 m) = 558 kN. Note that the gravitation force (weight) acting on the ...

parentheses is the dynamic amplification–the factor by which a load is amplified when suddenly imposed. Since the displacement and load are proportional the effective force carried by the beam during impact is the product of the dynamic amplification and the weight, W. Note that the dynamic amplification for V = 0 (Ek = 0 ) = 2: a load suddenly
