Average crush force exerted on a car

In summary, the average crush force exerted on a car can range from 100,000 to 200,000 pounds and is calculated by measuring the energy absorbed during a collision. It can vary due to factors such as speed, weight, impact angle, and structural design, and can affect occupant safety. However, it can be reduced through measures such as improving design and incorporating safety features.

Homework Equations


Kinetic energy = Ke = (1/2)(mv^2) (joules - J)
where m = mass (kg)
v = velocity (m/s)

The Attempt at a Solution


What I was thinking was that the kinetic energy is divided uniformly over the distance d and hence
Average crush force = mv^2 / 2d

But I don't know how to prove that. Of course I could try to explain it with words, but I don't feel that it is enough.

Thank you in advance.

All of the KE is converted to work in crushing things: W = Fd = 1/2*m*v^2

1. What is the average crush force exerted on a car?

The average crush force exerted on a car depends on various factors such as the weight and speed of the car, the type of collision, and the structural design of the car. However, on average, the crush force can range from 100,000 to 200,000 pounds.

2. How is the average crush force on a car calculated?

The average crush force on a car is calculated by measuring the amount of energy absorbed by the car's structure during a collision. This is typically done through crash tests and analyzing the deformation of the car's structure.

3. What causes the average crush force on a car to vary?

The average crush force on a car can vary due to several factors such as the speed and weight of the car, the angle and type of impact, and the structural design of the car. Additionally, the presence of safety features such as airbags and crumple zones can also affect the average crush force.

4. How does the average crush force on a car affect occupant safety?

The average crush force on a car plays a significant role in occupant safety. If the force is too high, it can cause severe injuries or even death to the car's occupants. However, with proper safety features and structural design, the average crush force can be reduced, thus increasing the chances of survival for the occupants.

5. Can the average crush force on a car be reduced?

Yes, the average crush force on a car can be reduced through various measures such as improving the structural design, incorporating safety features, and implementing stricter safety regulations. Car manufacturers also conduct extensive crash tests to ensure that their vehicles can withstand high impact forces and protect the occupants.
