“How can we determine the fracture strength and resistance of a material using simple devices?”
Determining the fracture strength and resistance of a material is of the utmost practical use to the engineering profession. However, how exactly can figure them out experimentally in a cost-wise fashion? Well, let’s think about this using our engineering mindset. We already know the strength of many other materials. And we also know that if one material is able to scratch another, then it is the stronger of the two. So what if we were to take this method and use it to organize all of the different materials we know? Well, this is the fundamental idea behind the scratch test, and it is used for economically conscious projects around the world.
