What type of loading conditions can be evaluated in material testing?

• Magnitude, cycling, and mode

• Static and dynamic

• Tensile, compression, and hardness

• Strength, deformation, and fracture

Which type of test applies a straight line axial force to a test sample?

• Compression test

• Tensile test

• Dynamic test

• Hardness test

What is the purpose of a tensile test?

• To determine the strength of a material

• To measure the hardness of a material

• To evaluate the ductility of a material

• To ensure meaningful and reproducible results

How can test data be manipulated to represent a material and not an individual test sample?

• By calculating sample stress

• By increasing the test sample size

• By decreasing the test sample size

• By calculating sample strain

What is the modulus of elasticity?

• The ability of a material to resist stretching

• An inherent property of a material

• All of the above

• A measure of stiffness

What happens to a test sample in the elastic range when the load is removed?

• It becomes stronger

• It returns to its original length

• It undergoes plastic deformation

• It fractures

What is the resilience of a material?

• The ability of a material to stretch without breaking

• The ability of a material to resist permanent deformation

• The ability of a material to resist scratching, wear, cutting or drilling

• The amount of energy per unit volume that a material can absorb while in the elastic range

What is the offset yield strength?

• The stress at which necking occurs

• The stress at which the elastic limit is exceeded

• The stress at which proportionality ceases

• The stress required to produce a tolerable amount of permanent strain

What is plastic deformation?

• Unrecoverable elongation beyond the elastic limit

• The stress required to produce a tolerable amount of permanent strain

• The ability of a material to resist permanent deformation

• The amount of stretch per unit length
