We express it with the below impact force equation. Impact Force can be expressed as division of mass and square velocity with 2 times time. As the resultant stress (σ) in the plate (≈44MPa) is extremely low for carbon steel, you could use a thinner plate or accommodate a greater impact force.PLATES – Distributed Load. g-Force Constant 1. gc = Learn how to use the impact force calculator with a step-by-step procedure. Question: 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. In this case the deformation is equal to 1 meter. In other words, cars are meant to crumple and deform because a slower acceleration, or in the case of a car crash, deceleration, is safer for a human body to endure. To create an equation for the force of any impact, you can Next, we need to determine the spring constant. This online force calculator helps you to determine the force of an object given the mass and acceleration values. v = v₀ + gt. Note that the gravitation force (weight) acting on the car is only.
