Example: An exercise bike that can support 250 lb. Does the engineer find a large enough weight that deforms the bike, then take a fraction of that as the amount it can support?
In: Engineering
People here are correct but it’s worth noting that the way these computer programs or tables people can use know how much weight a material with a given cross section can take is that an enormous number of tests have been done on that material to see how much force it can take before deforming.
So in a sense, yes. An engineer knows how much weight will deform each individual component of the bike from destructive testing and can then design based on that.
