Impact force to a human being

  1. Jul 17, 2015 #1
    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.

    Most injury criteria are in terms of force and pressure.

    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.
