What equation(s) do I use to calculate the weight necessary to crush a pipe lying horizontally on the ground and the point at which the initial deformation occurs. What is the name of this property? I'd like to compare my findings with a manufacturer's specs. I have a 3000 lb weight resting flat on four plates. Each plate is resting on 30 pipes that are lying side by side horizontally. Assuming that the weight is square, that each plate is flush with a different corner of the weight, and that each plate is 4" x 15", what is the force exerting on one pipe? Pipe Dimensions: Length = 4" Diameter = 0.5" Wall Thickness = .0625" Material = Steel It's been awhile since I've done statics.
