QUESTION: 1

### Which of the following parameters can be obtained by tension test of a standard specimen?

Solution:

Tension test determines the parameters related to stress strain curve and also reduction and elongation in area and length can be found respectively.

QUESTION: 2

### Proportional Limit is defined as the stress at which the stress strain curves begins to deviate from the straight line.

Solution:

Explanation: Proportional limit is the point of deviation in stress strain curve.

QUESTION: 3

### Which of the following is the definition of Compliance?

Solution:

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

QUESTION: 4

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

Solution:

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

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?

Solution:

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

QUESTION: 6

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.

Solution:

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

QUESTION: 7

Which of the following are true about plasticity?

Solution:

Explanation: This is the basic definition of plasticity.

QUESTION: 8

Which of the following is measure of stiffness?

Solution:

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

QUESTION: 9

Which of the following facts are true for resilience?

Solution:

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

QUESTION: 10

Modulus of resilience is defined as

Solution:

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