Answer:
The angular velocity is ![w= \sqrt[4]{\frac{a_{max}^2}{r^2} - \alpha ^2}](https://tex.z-dn.net/?f=w%3D%20%5Csqrt%5B4%5D%7B%5Cfrac%7Ba_%7Bmax%7D%5E2%7D%7Br%5E2%7D%20%20-%20%5Calpha%20%5E2%7D)
Explanation:
Generally the acceleration experienced by the propeller blade's is broken down into
The Radial acceleration which is mathematically represented as
And the Tangential acceleration which is mathematically represented as
The net acceleration is evaluated as
Now since angular speed varies directly with angular acceleration so when acceleration is maximum the angular velocity is maximum also and this point if the propeller blade's tip exceeds it the blade would fracture
So at maximum angular acceleration we a have
Answer:
Hello, the tripping of a 230-kilovolt transmission line.
Explanation:
the tripping of a 230-kilovolt transmission line near Ontario, Canada, at 5:16 p.m., which caused several other heavily loaded lines also to fail. Hopefully this helps you find what your looking for!.
Because many fuels are fossil fuels they take millions of years to form and the known reserves are being used much faster than the new ones being made
Answer:
Once used as a energy source they cannot be charged/used again.
Explanation:
1) they are attracting because if you look at the arrows they’re all pointing the same way.
2) if the magnet was turned around they would do the opposite and not attract ( this is called repulsion)
3) magnetic pole
4)magnet
5) magnetic force
6) magnetism
Hope this helps
