3. ductilty, yield strength
4. stiffness, yield strenght​

Answer 1

Answer:

ductility and tensile strength

Explanation:

option 1

Answer 2

Answer:

The material's toughness depends on ductility and tensile strength. So the right answer is an option (1).

Explanation:

• The basic property of a material that measures the material's ability to absorb energy and withstanding the shock up to fracture is said to be the toughness of the material.
• Often toughness is referred to as the ability to absorb energy within the plastic range.
• The mechanical property which allows a material to get drawn (e.g, into a wire) or get deformed without any fracture, is called ductility of a material.
• Tensile strength of the material is the maximum amount of load it can withstand without getting fractured when being stretched or divided by the real cross-section of that particular material.
• The material is said to lack toughness if it didn't go through a plastic deformation

So, the material is tough if it has a nice combination of tensile strength and ductility.
