Answer:
Because with this test you can determine complex material parameters like Young’s modulus, yield strength, ultimate strength and elongation at break. This is important because it provides us with the factor of safety that needs to be built-in the products using these materials.
Explanation:
This test consists in place the material between to tweezers to subdued the material into a stress-strain test. The figure shows the procedure.
In the x axe the strain and the y axe the stress.
Answer:
(a) Current density at P is 
.
(b) Total current I is 3.257 A
Explanation:
Because question includes symbols and formulas it can be misunderstood. In the question current density is given as below;
where 
and 
unit vectors.
(a) In order to find the current density at a specific point <em>(P)</em>, we can simply replace the coordinates in the current density equation. Therefore
(b) Total current flowing outward can be calculated by using the relation,
where integral is calculated through the circular band given in the question. We can write the integral as below,
due to unit vector multiplication. Then,
where 
. Therefore
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.
