 Which of the following is the definition of Compliance?

Detailed Solution: Question 3

Explanation: Compliance is a parameter which is the inverse of stiffness.

Test: Stress Strain Diagrams & Mechanical Properties - Question 4
Save

Yield strength is defined as the maximum stress at which a marked increase in elongation occurs without increase in________

Detailed Solution: Question 4

Explanation: Yield strength is the strength at which strain increases. Now as the strength is constant, therefore load is constant.

Test: Stress Strain Diagrams & Mechanical Properties - Question 5

For the materials which do not exhibit a well-defined yield points, the yield strength is defined as the stress corresponding to a permanent set of how much percentage of gauge length?

Detailed Solution: Question 5

Explanation: Generally for all the practical purpose, an offset of 0.2% of gauge length is considered.

Test: Stress Strain Diagrams & Mechanical Properties - Question 6
Save

 Proof strength is defined as the stress which will produce a permanent extension of how much percentage in the gauge length of the standard test specimen.

Detailed Solution: Question 6

Explanation: Proof strength is used in design of fasteners. It corresponds to 0.1% permanent deformation of gauge length.

Test: Stress Strain Diagrams & Mechanical Properties - Question 7
Save

Which of the following are true about plasticity?

Detailed Solution: Question 7

Explanation: This is the basic definition of plasticity.

Test: Stress Strain Diagrams & Mechanical Properties - Question 8
Save

Which of the following is measure of stiffness?

Detailed Solution: Question 8

Explanation: Stiffness is the ability of material to resist deformation under external load. Hence it is measured by modulus of elasticity.

Test: Stress Strain Diagrams & Mechanical Properties - Question 9
Save

Which of the following facts are true for resilience?

Detailed Solution: Question 9

Explanation: Toughness is ability to store energy till proportional limit during deformation and to release this energy when unloaded.

Test: Stress Strain Diagrams & Mechanical Properties - Question 10
Save

Modulus of resilience is defined as

Detailed Solution: Question 10

Explanation: Modulus of resilience is strain energy per unit volume.
