Materials and Mechanical Properties Quiz

What are the three main categories of materials that engineers work with?

• Plastic, Rubber, and Glass

• Aerogel, Graphene, and Steel

• Metals, Ceramics, Polymers

• Metals, Wood, and Stone

What are the mechanical properties of a material?

• How easily it can be dented, its resistance to creep, and fatigue strength

• How it reacts with the environment, cost, and appearance

• Its color, weight, and texture

• How much strain it undergoes given a certain amount of stress

What is the modulus of elasticity?

• The measure of how easily a material can be dented

• The highest possible stress a material can withstand a given number of times before failure

• The measure of how much a material resists a change in shape under an applied stress

• The amount of energy a material can absorb before failure

What is the Charpy impact test used for?

• Measuring the toughness of a material by striking it with a hammer

• Measuring the fatigue strength of a material

• Measuring the hardness of a material

• Measuring the creep strength of a material

What is creep strength in materials?

• How much a material can endure a certain amount of stress before failure

• How many times a material can endure a certain amount of stress before failure

• How much a material resists deforming under long term stress or extreme temperatures

• How easily a material can be dented

What is toughness in materials?

• How much a material resists deforming in a particular location

• How much a material can endure a certain amount of stress before failure

What is the yield stress in materials?

• The point at which a material breaks apart entirely and undergoes failure

• The amount of stress a material is subjected to before it undergoes a particular amount of strain

• The measure of how much a material resists a change in shape under an applied stress
