An "odd" avalanche...

[murilo]

Al_ex,
recently I made a rough experiment, through a simple build, where an obvious stuff become clear to see:

- a fulcrum and a single horizontal wood with two equal arms each side.

- at each edge, two equal lead fishing weights was hold.

- experiment: the set was forced to stay at vertical position, one at top, 12h, while other at button, 6h.

- after released, the vertical positioned set, very slowly, became free to AGAIN reach horizontal stability, 9h and 3h.

- before find horizontal rest, the 12h edge advanced down at least 15º under 9h.

- this wick force shown in those 15º fall is our so called 'g' acceleration... not a miracle but a 'gift' if you know to deal with.

- NOW, another good stuff if one think in 'avalanche': the opposite side offered only passive resistance but connected to other little stuff: inertia gain.

(one side active by 'g' while other side simple passive resistance!)

TC!

Hi Murilo !
We are living inside a natural mechanical energy amplifier:if mass is free to fall , between two gravitational levels you can see and fee momentuml.

Conceptually , there is no difference between the free fall of a single mass and the free fall of an unbalance (two masses couple of an imbalanced lever ).

This can be a manner to collect mechanical/kinetic energy , if we use momentum "like the snowflake becomes an avalanche"...

... or a free falling mass on a pulley... or a free falling inverted pendulum (here , with a heavy hub we can store rotational inertia ).

We can play so easy this kind of simple "rough experiments" ,to stimulate our imagination for some self-running devices , as :

Al_ex,
the device you sent uses unequal hammers, while my stupid one used equal weights to yet show acceleration .

At least to me, my little experiment was useful to SEE the 'power' shown in a 'graphic' way and with the use of equal potentials.

The only 'trick' was our so called 'g' and geometry.
Since I'm not Cartesian, I need and like to touch/smell this. B-)

Hi Murilo !
In your experiment , the center of mass related to fulcum , seems to be the main point regarding balance/unbalance , as you can see at :

Additionally , take a look at "Three points on a line..." topic.

In this manner you can (re) consider your experiment...this is my opinion.

Sorry, my friend!
I can't reach your mind.
Since the weights are the same, the 'rest' position should be only 90º, at 9h.
Merry Christmas to all!!!

Nice link Al_ex Thanks

There are a few points of the avalanche that has to be addressed. First is the top wheel has to spin several times faster than the bottom. You only have the amount of weight on the descending side to make all this happen. The descending above is not enough weight to pull the ascending side up due to linkage effect. So that force has to come from the upper wheel timed with the lower wheel by chain or gear. The other problem is the bunching applies a lot of force and there is no way to truly relieve enough force to take the parts from the bottom to be lifted up the ascending side.
The Basic approach is strong but a need of redesign is needed IMHO

Good luck
Alan

P.S. Marry Christmas to all, and to all future great success.

Alan,
be my guest! I need help as everybody knows!

That top wheel is to turn free and passively, moved by the armed chain segment that rises. Very simple.

If you take a 2 pan balance with, f.e., 2kg at a side and 1 kg at the other, you'll see that 1 kg will be free against your hand, when you hold or sustain lighter side.

In theory, under FREE 'g', the 'product' of one side cancels to the other, BUT if I keep all system NOT FREE but HOLD in low speed, every stuff will be different.

If I don't have a turning set in my room it's JUST due to those HOOKS that let chain to scape.

I don't need to lie and nothing to hide, Alan! I'm just a stupid builder... nothing else!
Best!

Hi Murilo my brother,

Keep the faith and Mother Earth will give you your Avalanche, what's one more Avalanche to a hard working mum!

Merry Christmas to you all.

[murilo]

Absolutely, my brother!
Absolutely!
Much more than faith I use TRUST/confidence!
Best of Seasons to you and your beloved!
TC!

Al_ex,
thanx for the link.
This is another same stuff or a known complicated project.

My stuff is now here:

BTW, I miss TREVOR, the good!

[Trevor Lyn Whatford]

Hi Murilo,

I miss you to Brov, I also miss Brazil very much, seeing Rio in the back ground of the football, brought back some good memories of the Beach, Sun, cool Beer, swimming, and the beautiful people enjoying it.

I will show you some of my latest experiment when I get the time. As you know it is not Ideas we are short of, it is time we need.

Take care Brov and hope life is being kind to you and your family.

With much respect Trevor the good!

[murilo]

Meu querido!
So good to know that you're around!

So good that you are here at least in good memories!

Be our guest, brov!

Yes... we have absolutely to deal with surplus of ideas and even avoid new projects... while some are dreaming... that they are guessing... that they are thinking... that they are figuring... that they are masturbating... B]

Abre o olho, Trevor, 'o baum'! B)))

This water tank looks like it uses your avalanchedrive.
Better tread shot starts at 11:30.

[murilo]

justalabrat, thank you indeed!
I'm very sorry since youtube sometimes doesn't work for me!
Tomorrow I'll try again!
Is there another way to see this?
For the other side, I kicked a green to you!
TC!
