In mechanics, compressive strength (or compression strength) is the capacity of a material or structure to withstand loads tending to reduce size (as opposed to tensile strength which withstands loads tending to elongate). In other words, compressive strength resists compression (being pushed together), whereas tensile strength resists tension (being pulled apart). In the study of strength of materials

2020.11.18 Oh man, that's a FEA job. all other calculations as realtively simjlistic and amke some assumptions about the tube that you don't have. Also there a massive difference between a rope / sling which is a distributed load and "hook" which implies really high point loads. But I don't know why you're bothered. if the tube flattens then so what?

2022.12.15 Ect is a measure of the edgewise compressive strength of corrugated board. It is measured by compressing a small segment of board on edge between two rigid. Enter the edge crush test (ect), the box perimeter (in), and the box thickness (in) into the box crush test (bct) calculator. Strengths (sct or rct), we can calculate the expected
