1. Fatigue equations are based solely on theoretical assumptions. Experimental data is only used to verify the theory. a. True.b
Rainbow [258]

Answer:

1.  b. False

2. b. False

3.  b. False

4.  b. False

5. a. True

6. a. True

7.  b. False

8.  b. False

9. a. True

Explanation:

1. The fatigue properties of a material  are determined by series of test.

2. For most steels there is a level of fatigue limit below which a component will survive an infinite number of cycles, for aluminum and titanium a fatigue limit can not be defined, as failure will eventually occur after enough experienced cycles.

3. Although there is a cyclic stress, there are also stresses complex circumstances involving tensile to compresive and constant stress, where the solution is given into the mean stress and the stress amplitude or stress range, which is double the stress amplitude.

4. Low‐cycle fatigue is defined as few thousand cycles and high cycle fatigue is around more than 10,000 cycles.

5. The number of cycles for failure on brittle materials are less and determined compared with the ductile materials.

6.  The bending fatigue could be handled with specific load requirements  for uniform bending or axial fatigue of the same section size where the material near the surface is subjected to the  maximum stress, as in torsional fatigue, which can be performed on  axial-type specially designed machines also, using the proper fixtures if  the maximum twist required is small, in which linear motion is changed to rotational motion.

7.  A SN-Curve for a given material, is a plot displayed on logarithmic scales of the magnitude of an alternating stress in relation to the number of cycles to failure

8. The strain life method measures the strain resistance of local stresses and strains around stress concentration that controls the fatigue life of the material. It is more accurate than determining fatigue performance as the stress-life method is for long life millions of cycles in elastic stresses, but an it gets an effective stress concentration in fatigue loading.

9. Linear Elastic Fracture Mechanics (LEFM) states that the material is isotropic and linear elastic so, when the stresses near the crack surpasses the material fracture toughness, the crack grows.

Conversion of a continuous stream of sound into a series of ones and zeroes that can be interpreted by computers results in
gayaneshka [121]

Answer:

Conversion of a continuous stream of sound into a series of ones and zeroes that can be interpreted by computers results in  digital audio.

Explanation:

Digital audio is a portrayal of sound recorded in, or changed over into, digital structure. In digital audio, the sound flood of the audio signal is encoded as numerical examples in a persistent arrangement. In a digital audio framework, a simple electrical sign speaking to the sound is changed over with a analog-to-digital converter (ADC) into a digital sign, regularly utilizing beat code adjustment. This digital sign would then be able to be recorded, altered, adjusted, and replicated utilizing PCs, audio playback machines, and other digital apparatuses. At the point when the sound specialist wishes to tune in to the account on earphones or amplifiers (or when a shopper wishes to tune in to a digital sound record), a digital-to-analog converter (DAC) plays out the opposite procedure, changing over a digital sign go into a simple sign, which is then sent through an audio power intensifier and at last to an amplifier. Digital audio is an innovation that is utilized to record, store, control, create and repeat sound utilizing audio flags that have been encoded in digital structure. It likewise alludes to the grouping of attentive examples that are taken from a simple audio waveform. Rather than a consistent sinusoidal wave, digital audio is made out of careful focuses which speak to the sufficiency of the waveform roughly. The more examples taken, the better the portrayal, and henceforth impacts the nature of the digital audio. Most present day sight and sound gadgets can just process digital audio, and on account of mobile phones requiring simple audio input, they despite everything convert it to digital before transmission.
