Calculating Impact Forces on a Human Being Struck by a Moving Vehicle

In summary, the conversation discusses the calculation of pounds per square inch force on a female human being who is approximately five feet tall and weighs 185 pounds when struck by a moving vehicle with a curb weight of 2700 lbs at 4 mph. It is a complicated question that is often consulted by experts in biomechanics during traffic incidents resulting in lawsuits. However, force and pressure may not necessarily provide the most useful information, as energy and momentum may be more telling. Impact injuries may also give a better idea of the likely impact forces and velocities.

How do you calculate the amount of pounds per square inch force on say a female human being approximately five feet tall at 185 pounds at rest being struck by a moving vehicle at motion by gravity with a curb weight of 2700 lbs going 4 mph.

It's a complicated question that requires lots of details not given.

Experts in biomechanics get paid lots of money to consult on these questions when traffic incidents result in lawsuits.

Also, force (or pressure) isn't necessarily a useful thing to know. Energy and momentum probably tell you more.
 
  • #4
Most injury criteria are in terms of force and pressure.

As I understand it they

As I understand it they look at how far the person travels after impact and can only give a very rough idea of the likely impact forces and velocities.

I think you get a better idea from the impact injuries.
 

1. What is impact force to a human being?

Impact force to a human being is the amount of force that is exerted on a person's body when they come into contact with an object or surface. It is measured in units of Newtons (N).

2. How is impact force calculated?

Impact force is calculated by multiplying the mass of the object or surface by its acceleration. This can be represented by the equation F=ma, where F is the force, m is the mass, and a is the acceleration.

3. What factors affect the impact force on a human being?

The impact force on a human being can be affected by various factors such as the mass and velocity of the object or surface, the surface area of contact, and the elasticity of the object or surface.

4. How does impact force affect the human body?

Impact force can cause injuries to the human body depending on its magnitude and duration. It can result in bruising, broken bones, concussions, and other serious injuries.

5. How can the impact force on a human be reduced?

The impact force on a human can be reduced by increasing the duration of the impact, increasing the surface area of contact, and wearing protective gear such as helmets, padding, or seatbelts. Additionally, controlling the velocity and mass of the object or surface can also help reduce impact force.
