1. Stress concentration occurs due to

2. The approximate relationship between endurance limit of rotating beam specimen (S’e) and ultimate tensile strength (Sut), in case of steel component, is

3. The relationship between endurance limit of component subjected to fluctuating torsional shear stresses (Sse) to endurance limit in revered bending (Se) is

4. A stress that varies in sinusoidal manner with respect to time from a minimum value to maximum value and which has some mean as well as amplitude value is called

5. A stress that varies in sinusoidal manner with respect to time from tensile to compressive (or vice versa) and which zero mean is called

6. In cyclic loading, the effect of stress concentration is more serious in case of

7. Fatigue failure results due to fluctuating stresses when the stress magnitude is

8. Stress concentration occurs due to
