re: energy producing experiments

is that talk about the same?
mechanical device Kapanadze.

The Administrator is welcome to remove the kolbacict post. I thought I would post again so first timers see something that is on subject.

Look at the last statement:  My point is: one way to make energy is to combine a modified Atwood's with a rotating balanced beam.

You start with a modified Atwood's. You have a 4 kg block on dry ice. The block is tied to a string that is draped over a pulley that has a 1 kg mass suspended from the other end.

The acceleration is 1 kg / 5 kg * 9.81 m/sec² = 1.962 m/sec²

The one kilogram is allowed to accelerate toward the floor for one meter. This also means that the 4 kilograms on the dry ice will accelerate for one meter at a rate of 1.962 m/sec.

After the one kilogram has dropped one meter you have 4 kilograms moving horizontally on dry ice at 1.9809 m/sec.

And you have 1 kg moving down at 1.9809 m/sec.

We then change the direction of the one kilogram and have it moving on a horizontal plane. Let's direct the one kilogram so that it is moving in the opposite direction of the 4 kilograms.

So we have a 4 kg mass moving east on a frictionless plane. About a meter under it we have a 1 kilograms mass moving west.

At this point we connect the two moving masses to each end of a massless beam a meter long.

On this beam the two masses will rotate about their center of mass but the 'tangent velocity' of each mass will not remain the same. The total 'tangent' momentum will remain the same but the individual velocities will not.

The momentum of the one kilogram after it has dropped one meter is 1.98 m/sec * 1 kg = 1.98 units of momentum. The 'tangent' momentum of the one kilogram as it enters the rotation on the beam is 1.98 kg m/sec.

The momentum of the 4 kg is (4 kg * 1.98 m/sec = 7.9236) 7.9236 kg m/sec.

The total momentum is 7.9236 kg m/sec + 1.98 kg m/sec = 9.9 kg m/sec.

When an object is rotating about its center of mass it is also rotating about its center of 'tangent' momentum. So the 1 kg has half the momentum so it will be moving 4.95 m/sec.

The total momentum of the beam remained 9.9 kg m/sec.

At 4.95 m/sec the one kilogram can rise 1.25 m.

If the 1 kg is given all the momentum, as in the cylinder and spheres, it will rise; d = ½ v²/a;  5 m

So we start with a modified Atwood's machine and then we place those masses in a massless beam. We then arrange for a cylinder and spheres event and we get a 500 % increase in energy.

I am going to point out your errors as they occur.

A line does not have to be straight; that is the whole point of curvilinear and rectilinear. You have at least two types of lines; curved and straight. You can't properly look at Newtonian physic and have an improper definition of line. Your side want to set up a difference set of rule for mass moving in a circle; but Newtonian physics is about mass that is often moving in a circle.

Florens quote:  "It will also have to spin at a larger radius, so, by the law of levers it will decrease its speed, because v/r is constant."

Wrong: not if you are talking linear v. This is where your misconception of linear messes you up every time.  Linear speed does not care one iota about r. It is the same as changing direction; you can change direction with a long pendulum or a short pendulum. You are not going to change v by using a long or short r.

The common misconception with an Atwood cylinder
is that they think they observe a gain in energy
due to an observation made from the velocity of the
rolling cylinder.


In actuality this has more to do with aerodynamics of rolling cylinders.
and why the cylinder-plane flies.


Momentum is conserved, even in an Atwood

[Delburt Phend]

I did not know that an Atwood's (machine) had anything to do with a cylinder. Honestly what are you talking about?

[sm0ky2]

Oh...  ok so history for the chronologically gifted


Well some time after the death of Atwood,
his knowledge was advanced as far as science could
(a pully is generally cylindrical)


The most advanced form took place in space
in microgravity, using a cylinder and 2 spheres
on strings, that wound around the cylinder (pulley)


Different masses were tested etc.
