Item: Given the following information: Typical bone fracture force: 90kN 50% fatal on head accelerations if 150 g for 4ms & 50g for 60ms 50% fatal if whole-body pressure exceeds 3.4 Times 10 exp 5 N/meter squared Steering column distance = 0.3 m Front surface area of whole-body = 0.8 meter squared Head and chess surface area = 0.5 meters squared Consider a 75-kg passenger not wearing a seat belt traveling at 27m/s (60mph) who comes to rest in 0.010 seconds (car hits a brick wall) after striking in unpadded dashboard Calculate the average force of impact. Calculate the average acceleration in units of "g." (How many "g"?) Calculate the average pressure if head and chest hit dashboard For the driver, what average force is required to stop the driver to avoid hitting the steering wheel?
