Satisfactory Essays

This video tries to help people understand what defines strength by testing the world’s strongest materials known to men today, materials such as Kevlar, carbon nanotubes, and even some natural materials that are found in nature like the beak of the toucan and spider silk. Materials strength can be looked at in different ways. Materials strength is tested and checked in different types of strength like compression strength in glass and chalk, and tensile strength like in metals; most of this according to video can be explained by the atomic structure of materials.
