One thing that keeps getting to me when thinking about Simulation, is how abstract a Newton is.

Does anybody have experience on some ballpark figures for typical situations such as:

• An average person's pushing force
• An average person's pulling force
• An average person's lifting force
• A strong peron's pushing/pulling/lifting force
• A person's stamping force with his feet

All of these are likely the kinds of forces you will want to consider in most products.
