DIY Rotation Bar (Rotation wave)

[thc]

Hi,

Juz completed another DIY toy, the rotation bar. It works fine, turn quite fast. Check out the last two pics DIYs

huh how u make it rotate?? dun understand.. then the two sides must be attached to an axle??

[thc]

Later i'll 'let the cats out'..

[blueheaven]

ya i also want to know the mechanism :lol:

[tropic]

PICTURES AND DETAILS!!! was curious too how these rotating thingy works...mayb have bearing inside...??

[giantbicycle]

heyheyhey..where's the CATS???come on.. YEs,definaly there is bearing..or the axle keeps spinning ...Who knows ... DETAILS PLS>>

The cats are out. It's so simple you'll laugh

Rotation bar

huh? don't understand.. how does that make it turn?

Water flowing out in opposite direction from the T-bar. look closely at the pic, you'll see 5 holes on each side of the T-bar

OMG!!!! *faint*

Bro,

Still don't understand how it rotate.

If you have a rotation wave (from Octopus bay), you'll understand how it works

newton's 3rd law of motion: for every action, there is equal and opposite reaction

so the water pushing out from the holes is pushing the pipe the other way so it just turns round and round

Left school long time ago (at least 10 yrs), forgot all about that. Yup that's the theory. Thank for the help bro.

couple forces. the water flows out of the T bar in oppiosite directions at different sides of the T joint thus making it move.

But is the water flow fast enough to make it turn? the little ring u used, what is it? it lets the T bar turn?

[thc]

Yup, it does allow the T-bar to turn and it is turning at quite a speed.

If you have been to LCK 110, they have the same rotation bar (only bigger). That's the speed my rotation bar is turn at.

The speed of the rotation is equals to the pump pressure + number of holes ?

WAH !!! helicopter in the tank .....

wait it turn so fast that the fish no time to siam, pop than you have some unconscious fish lying somewhere hahahha

Quite true, that why it is not going into my main tank. It'll be in my next DIY.
