A 10 Kg load is applied to the diamond, the displacement if the diamond indenter is recorded and then the load is increased to 150 Kg.Bolts and screws are better suited for tension applications.Fastenings used in traditional wooden boat building, such as copper nails and clinch bolts, work on the same principle as the rivet but were in use long before the term rivet was introduced and, where they are remembered, are usually classified among nails and bolts respectively.Often, I need to know the yield and ultimate stress of materials when given only the Rockwell C hardness.NIKE2D can be used to calculate the Rockwell C hardness of various materials in the Database.
