In a tensile test on a steel specimen, true strain is 0.171 at a stress of 263.8 MPa. When true stress is 346.2 MPa, true strain
swat32

Answer:n=0.973

Explanation:

Given

When True strain\left ( \epsilon _T_1\right )=0.171

at \sigma _1=263.8 MPa

When True stress\left ( \sigma _2\right )=346.2 MPa

true strain \left ( \epsilon _T_2\right )=0.226

We know

\sigma =k\epsilon ^n

where \sigma=True stress

\epsilon=true strain

n=strain hardening exponent

k=constant

Substituting value

263.8=k\left ( 0.171\right )^n------1

346.2=k\left ( 0.226\right )^n-----2

Divide 1 & 2 to get

\frac{346.2}{263.8}=\left ( \frac{0.226}{0.171}\right )^n

1.312=\left ( 1.3216\right )^n

Taking Log both side

ln\left ( 1.312\right )=nln\left ( 1.3216\right )

n=0.973

qaws [65]

Answer:

In these present generation, every day a new technology is coming. People are adopting these technologies very fast. If we think ," we have learned C language , now why to worry about java " . Then that is called you are bounding yourself to a technology. You are not ready for the growth.

With the invent of new technologies, if we have basic idea of how it works, we can simply implement it. At the end of day , it doesn't really matter how many lines of code you have written , it is just about efficiency. How Efficiently you are writing your code.

So, When Efficiency is the only thing that matters to the organizations , they are ready to take up new technologies and they will try to work-out with them. This is the trend in IT .Every month a new technology comes, respective people will be trained on that and they will implement/migrate the existing projects into new efficient model.

If we really learn and implement things using advance technologies , people will get an exposure to new technologies as well as the organization will get good impact on them , for spending resources on learning new technologies in the market. Apart from that , everyone will be happy for adopting new stack of technologies for them.

If we observe the existing technologies:

Programming languages are :

C, JAVA, PYTHON,R , SCALA

web development technologies:

HTML,CSS , JAVASCRIPT, ANGULAR,REACT , BOOTSTRAP , NODE.JS, MongoDB....etc

databases skills:

SQL, oracle,mySQL, postgres and so many cloud databases also available.

So, there are plenty of opportunities that are available . There are life time courses available to learn new technologies.

LEARN..RELEARN....UNLEARN

this is the motto of many organizations. They simply learn one technology and they'll forget it . If something new comes, they'll learn and implements it.This is the current trend in software industry.

A liquid refrigerant (sg=1,2) is flowing at a weight flow rate of 20,9 N/h. Refrigerant flashes into a vapor and its specific we
Iteru [2.4K]

Answer:

Explanation:

volume of 20.9 N

= 20.9 / 11.5 m³

= 1.8174 m³

In one hour 1.8174 m³ flows

in one second volume flowing = 1.8174 / 60 x 60

= 5 x 10⁻⁴ m³

Rate of volume flow = 5 x 10⁻⁴ m³ / s .

What is an advantage of a nuclear-fission reactor?.
Kobotan [32]

Answer:

Nuclear fission is almost 8,000 times more efficient than traditional fossil fuels at producing energy. That's a lot of energy packed into a small space. Nuclear energy is more efficient, which means it uses less fuel to power the plant and produces less waste.


advantages:
-produces no polluting gases
-does not contribute to global warming
-very low fuel costs
-Low fuel quantity reduces mining and transportation effects on environment
-High technology research required benefits other industries
-Power station has very long lifetime

Disadvantages:
-Waste is radioactive and safe disposal is very difficult and expensive
-Local thermal pollution from wastewater affects marine life
-Large-scale accidents can be catastrophic
-Public perception of nuclear power is negative
-Costs of building and safely decommissioning are very high
-Cannot react quickly to changes in electricity demand
