Death by crushing or pressing is a method of execution that has a history during which the techniques used varied greatly from place to place generally involving the placement of intense weight upon a person with the intent to kill This form of execution is no longer used by any governmentThe compressive strength is measured by breaking cylin drical concrete specimens in a compression testing machine The compressive strength is calculated from the failure load divided by the cross sectional area resisting the load and reported in units of pound force per square inch psi in US Customary units or megapascals MPa in SI units
