One mechanical property of a structural material is indentation hardness, which is a measure of its ability to resist deformation when squeezed by force.Diamond is harder than steel, harder than gold, harder than wood, and harder than packing foam.Among the many engineering tests used to determine hardness, such as the Mohs hardness used in gemology, the Brinell test is one of them.Its concept is simple: a hard metal ball bearing is pressed A cikin gwaji na gwaji tare da wani karfi.munasumiyar diamita daga cikin madauwari wanda kwallon kafa bayan Ball.The Brasker Hardy yake amfani da tsarin lissafi; Da wuya magana, mafi girma ramin da ƙwallon hits, da maɗaurin abin duniya.in na wannan gwajin, HW sau 23 ya fi tsayi fiye da itace na halitta.
