Select the WRONG statement:

Detailed Solution: Question 2

The effect of stress concentration is more severe in case of brittle materials, due to their inability of plastic deformation. Brittle materials do not yield locally and there is no readjustment of stresses at the discontinuities.

The selection of the factor of safety in design is not dependent upon:

Test: Design Against Fluctuating Load - 2 - Question 5
Save

Failure of a material is called fatigue when it fails

Detailed Solution: Question 5

Fatigue failure is characterised below the yield point.

Test: Design Against Fluctuating Load - 2 - Question 6
Save

The fatigue life of a part can be improved by

Detailed Solution: Question 6

Shot peening is the process of producing residua! compressive stress within the material which leads to increase in fatigue life of the component.

Test: Design Against Fluctuating Load - 2 - Question 7
Save

The severity of stress-concentration can be reduced

Detailed Solution: Question 7

In practice, reduction of stress concentration is achieved by following methods.
1. By providing additional notches and holes intension member
2. By drilling additional holes for shaft
3. By providing a small undercut in threaded member

Test: Design Against Fluctuating Load - 2 - Question 8

If the size of a standard specification for fatigue testing machine is increased the endurance limit for the material! will

Detailed Solution: Question 8

In the diameter or size of the components is more the surface area will have greater number of surface defect. Hence endurance strength of component reduced with increase in size.

Test: Design Against Fluctuating Load - 2 - Question 9
Save

Stress concentration factor is ratio of

Detailed Solution: Question 9

Fatigue stress concentration factor can be defined as the ratio of endurance limit without stress concentration to the endurance limit with stress concetration.

Test: Design Against Fluctuating Load - 2 - Question 10
Save

Resistance to fatigue of a material is measured by

Detailed Solution: Question 10

Endurance iimit is term defining the fatigue resistance of material.
