Thanks for your response, Greg. Correct-- I'd like to know the impact force delivery to the speed bump. How would you go about this calculation? Please be detailed. Note: Not an engineer, but moderately quantitative. Assumptions: Normal sedan, suspension, tires, etc.; weighs 3000lbs Assume 50/50 weight distribution (I know it's not) Driving 10mph Speed bump is 1ft long, 1in high (I know, small) **Assume each tire has a 100in2 contact patch (10x10in). Questions: What would your thought process be? Please be detailed. What's the right unit of measurement? lbs/square inch? Considerations / missing information? Thinking the suspension might come into play... anything else? What would some good assumptions be?

Hello All, Long time reader, first time poster. Not an engineer. Problem: A car drives over a speed bump. How much weight rolls over the speed bump per axle? Assumptions: Normal sedan, suspension, tires, etc.; weighs 3000lbs Assume 50/50 weight distribution (I know it's not) Driving 10mph Speed bump is 1ft long, 1in high (I know, small) Questions: What would your thought process be? Please be detailed. What's the right unit of measurement? lbs/square inch? Considerations / missing information? Thinking the suspension might come into play... anything else? What would some good assumptions be? Note: This is not a work or academic related problem-- Just something I'm curious about. Thanks, John
