The first one is the answer
Answer:
The speed of shaft is 1891.62 RPM.
Explanation:
given that
Amplitude A= 0.15 mm
Acceleration = 0.6 g
So
we can say that acceleration= 0.6 x 9.81
![acceleration,a=5.88\ \frac{m}{s^2}](https://tex.z-dn.net/?f=acceleration%2Ca%3D5.88%5C%20%5Cfrac%7Bm%7D%7Bs%5E2%7D)
We know that
![a=\omega ^2A](https://tex.z-dn.net/?f=a%3D%5Comega%20%5E2A)
So now by putting the values
![a=\omega ^2A](https://tex.z-dn.net/?f=a%3D%5Comega%20%5E2A)
![5.88=\omega ^2 \0.15\times 10^{-3}](https://tex.z-dn.net/?f=5.88%3D%5Comega%20%5E2%20%5C0.15%5Ctimes%2010%5E%7B-3%7D)
![\omega =198.09\ \frac{rad}{s}](https://tex.z-dn.net/?f=%5Comega%20%3D198.09%5C%20%5Cfrac%7Brad%7D%7Bs%7D)
We know that
ω= 2πN/60
198.0=2πN/60
N=1891.62 RPM
So the speed of shaft is 1891.62 RPM.
Answer:
Explanation:
Enforcing OSHA, Occupational Safety and Health Administration, standards is not a job for electricians, lawmakers or tax collectors. The right answer is safety inspectors.

Answer:
True
Explanation:
Actually this are some of the nitty gritty answers and ways to control or stip stress, lemme explain them you see stress most of the time may come from deep thoughts that are and are pushing you to the wall, and you in your state you as you react to that which is so demanding as it makes you tense,so if at you will incorporate physical activities like running, jogging or push ups the psychological tension in you is broken as you focus so much on the activities rather than the tension, then getting enough rest cools the mind and all your thoughts settle as in your brain starts to adapt to chilling and relaxation and enough sleep will actually make ones head to be at peace because if you lack enough sleep you might have an excruciating migraine when you are stressed up and finally relaxation techniques makes the body accept the situation and then you manouver out of it as you grow strongly.
Hope this will help!
