Mechanical Properties Quiz

What is a mechanical property?

• A characteristic of a material that describes its behavior under applied forces or stress.

• A property that describes the color of a material.

• A property that determines the electrical conductivity of a material.

• A characteristic that defines the thermal expansion of a material.

Which of the following is NOT a mechanical property mentioned in the lesson?

• Plasticity

• Elasticity

• Conductivity

• Hardness

Which mechanical property is important for a material to return to its original shape after deformation?

• Plasticity

• Elasticity

• Hardness

• Stiffness

Which mechanical property is considered most important among the options below for designing a bridge?

• Flexibility

• Strength

• Elasticity

• Ductility

Why is strength considered the most important mechanical property for designing a bridge?

• It allows the bridge to bend easily.

• It helps the bridge to support heavy loads without breaking.

• It makes the bridge more elastic.

• It increases the bridge's aesthetic appeal.

What is the definition of elasticity?

• Permanent deformation, does not return to original shape after yield point.

• Temporary deformation, returns to shape when stress is removed.

• Ability to conduct electricity.

• Resistance to corrosion.

Which testing method is used to measure elasticity?

• Yield Strength Test

• Hardness Test

• Elastic Modulus Test

• Impact Test

Which of the following is an example of an elastic material?

• Clay

• Aluminum

• Rubber

• Glass
