Question 1:
Which of the following is a mechanical property of a material?
Explanation: The correct answer is B) Hardness. Hardness is a mechanical property that describes a material's resistance to deformation, indentation, or scratching. It relates to the material's ability to withstand external forces without permanently deforming.
Question 2:
Which mechanical property describes a material's ability to resist being pulled apart?
Explanation: The correct answer is B) Ductility. Ductility is a mechanical property that describes a material's ability to be elongated or stretched without breaking when a tensile force is applied. It relates to the material's ability to resist being pulled apart.
Question 3:
Which mechanical property describes a material's ability to return to its original shape after deformation?
Explanation: The correct answer is C) Elasticity. Elasticity is a mechanical property that describes a material's ability to return to its original shape after deformation when the external force is removed. It relates to the material's ability to recover its initial form.
Question 4:
Which mechanical property describes a material's ability to absorb energy without fracturing?
Explanation: The correct answer is B) Toughness. Toughness is a mechanical property that describes a material's ability to absorb energy without fracturing. It relates to the material's resistance to crack propagation and its ability to withstand impact or sudden loading without breaking.
Question 5:
Which mechanical property describes a material's ability to be hammered or pressed into different shapes without breaking?
Explanation: The correct answer is B) Malleability. Malleability is a mechanical property that describes a material's ability to be hammered or pressed into different shapes without breaking. It relates to the material's capability to undergo plastic deformation under compressive forces.
