Question 1:
Which mechanical testing method is used to measure a material's resistance to indentation?
Explanation: The correct answer is C) Hardness testing. Hardness testing measures a material's resistance to indentation or scratching. It provides information about the material's strength and wear resistance.
Question 2:
Which mechanical testing method is used to measure a material's ability to withstand pulling or stretching forces?
Explanation: The correct answer is A) Tensile testing. Tensile testing measures a material's ability to withstand pulling or stretching forces. It provides information about the material's strength, ductility, and elasticity.
Question 3:
Which mechanical testing method is used to measure a material's ability to absorb energy during sudden loading?
Explanation: The correct answer is B) Impact testing. Impact testing measures a material's ability to absorb energy during sudden loading. It evaluates the material's toughness and resistance to brittle fracture.
Question 4:
Which mechanical testing method is used to evaluate a material's resistance to repeated cyclic loading?
Explanation: The correct answer is D) Fatigue testing. Fatigue testing evaluates a material's resistance to repeated cyclic loading, which can lead to failure over time. It assesses the material's endurance limit and fatigue strength.
Question 5:
Which mechanical testing method is used to measure a material's resistance to permanent deformation under compressive forces?
Explanation: The correct answer is D) Compression testing. Compression testing measures a material's resistance to permanent deformation under compressive forces. It assesses the material's compressive strength and modulus of elasticity.
