Explanation:
On EDG
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.
