A designer of football helmets has two options for increasing the safety of helmets but for economic reasons can implement only one. One option is to double the area of contact that will be experienced in a helmet-to-helmet collision. The other is to double the crumple distance experienced in a helmetto-helmet collision. Which will be more effective in reducing the maximum stress?
