### Impact Force Calculation

Mar 14, impact is a transient event so inertial effects (mass/density) play a critical role in determining the forces (analytically in simple elastic impact sort of situations; numerically, otherwise). it does not seem like you are interested in impact. instead, it seems you are interested in contact.The above equation can be used to calculate both impact force of a falling ojbect as well as impact force of a horizontally-moving object such as in a car crash or plane crash. the formula can easily be extended to calculate the approximate maximum impact force (a.k.a. peak impact force) by multiplying the resulting average impact force by.

### Impact Force

The impact force can be calculated as. f max = 1/2 ( kg) (16.7 m/s) 2 / (0.5 m) = 558 kn. note that the gravitation force (weight) acting on the car is only. f w = m g = ( kg) (9.81 m/s 2) = 19.6 kn. the impact creates a force 28 times gravity!! a person sitting inside the car with seat belts on will de-accelerate with a force 28 times.The principles used for impact loading is the time for the natural frequency of the body is much greater than with the time for applying force on materials. since the hammer is rotating at a very.
