Answer the following question given this paragraph: 

makes it clear that the deformation is proportional to the applied force. Figure 5.13 shows the Hooke’s law relationship between the extension ΔL of a spring or of a human bone. For metals or springs, the straight line region in which Hooke’s law pertains is much larger. Bones are brittle and the elastic region is small and the fracture abrupt. Eventually a large enough stress to the material will cause it to break or fracture. Tensile strength is the breaking stress that will cause permanent deformation or fracture of a material. Hooke’s Law.


Q: What term refers to the breaking stress that will cause permanent deformation or fracture of a material?


A:
tensile strength
