Impact Force - Engineering ToolBox

The impact on a human body can be difficult to determine since it depends on how the body hits the ground - which part of the body, the angle of the body and/or if hands are used to protect the body and so on. For this example we use an impact distance of 3/4 inch (0.0625 ft) to calculate the impact force: F avg = (800 ft lb) / (0.0625 ft ...Read more
