Final answer:
The three strength characteristics important for cutting tools are compressive, tensile, and transverse rupture, as seen in materials like rocks and metals.
Explanation:
Strength characteristics important for cutting tools are compressive, tensile, and transverse rupture. Compressive strength refers to the ability to withstand compression forces, tensile strength is the resistance to stretching forces, and transverse rupture is the ability to resist shear forces.
For example, in rocks, it's easier to break them by pulling apart (tensile strength) than by squeezing them (compressive strength). Understanding these strength properties is crucial for designing effective cutting tools.
Materials like metals exhibit properties like malleability and ductility, which determine how much deformation they can undergo without breaking, enabling them to be shaped into wires or hammered without fracturing.
