Quick question isn't the 2d test not accurate?. With the normal experiment, you have gravity as a constant and giving it acceleration. There is no way humans can provide the same force with the same consistency.

Good arguments. Just concerned with the practical 3d experiments, each 3d experiment here is being given a head start, pulling (or whipping) the chain up to begin with. The Mould effect should be a self-rising effect, right? Steve's demonstrations typically start by pulling the chain over the edge without pulling up to begin with.

You're both wrong but have some parts right! :D It is indeed the built up momemtum from gravity that gets it lifted vertically out of the bowl (this also happens for other chains, though not as far). The reason it goes so far for the ball chain is that it takes more energy/force it it to change direction / unit time. When speed increases, so that the unit time decreases, since the angular velocity remains constant, the radius of curvature is forced to increase. Other chains have a higher constant angular velocity (takes less force to bend) which means their mould effect is less / not there.

This has already been settled. You can't get higher authority than Cambridge physicists. Anyone can be wrong, but this is a very basic and simple problem for them. There are more difficult problems in undergrad interviews.

Well, I don't understand how one would think that the floor test demonstrates the "Mould Effect". When testing on the floor, the top of the arc, the point where the direction of the chain changes, does not move further from the end of the chain but closer to it! What Mehdi shows in the floor test is NOT the "Mould Effect". If you want to demonstrate the effect on the floor, you also have to add a constraint that simulates the lip of the bowl / glass!

You spend a lot of time saying why Steve is wrong but don't even give your own explanation! You say that the time to go around the loop is constant and I wanted the whole video for you to say why and you just didn't. You only have a small part of an explanation and even that is wrong. Here is why you are wrong: 1. You say that the chain takes the same amount of time to be accelerated around the loop, but if you look at the Mould effect working, the turning happens just at the top of the fountain, it is relatively straight before that. 2. Not only did you not explain why the time should be constant, your experiment clearly shows that it is not true, and you draw a false conclusion from it. Clearly the higher drop height takes longer. 3. You don't give any explanation as to where the extra force is coming from to push up the chain. If it's not coming from the lever effect, it has to come from somewhere. 4. You claim the Mould effect works for a normal chain but in your floor test the turning point of the chain moves backwards, not forwards, it just doesn't move backwards as fast as the point the chain is being pulled from, but if you drew a beaker there on the floor you would see that it doesn't make it over the beaker. 5. The same is true when you say the Mould effect works with the bead chain when it can't push against any surface, the Mould effect is not happening there, the point of turning is still moving backwards in absolute terms, even though there is a slight Mould effect from ground friction with the point the chain is being picked up. 6. Again, when you do your fish wire test, the point of turning moves downwards, not upwards, that is not the Mould effect. The reason is would stay in the same place is the effect of chains moving through their shapes that Steve explains in his video. 7. Your 'hose Mould' effect is a completely different effect. This only happens when the hose is about to run out, because the previous equilibrium is broken by there being less weight for the hose to drag but the same force/speed pulling it forward, so it overshoots. The Mould effect happens when the chain is not about to run out. 8. You say that a normal chain should still work as a lever, and that is true, but the effect is small since each link can only leverage its own weight when being lifted, as it can freely love around the next link. With the bead chain, there is a minimum curvature that the chain can go through, and when the chain is being lifted quickly, this is being pinched, meaning it puts a large force downwards to avoid the curvature, so the difference is that the force can be transferred between links. 9. You said on your comment of Steve's video that you are insure of the bullet on the block being real because of energy. When the bullet hits on the edge, that part of the block moves more easily than when it hits the middle, meaning it is as if it's hitting something lighter, which means more energy is transferred to the block, because the bullet will go in less far giving less energy to breaking bonds in the block, or if they are rigid, it will bounce off with less kinetic energy.

I'm neither an electrical engineer nor a mechanical engineer, so I'm more qualified than both. It is the same mechanical phenomenon as when waving whiplash. A wave that moves from one end to the other. In a whiplash, the energy moves from one side to the other and one end is static. In these cases the top of the wave appears to be static for the observer. It is the starting side that moves / falls. There is a difference in observation not the phenomenon. Why is the chain rising? Or you can put it this way, why the wave gets bigger. The answer is the same as a whiplash. If you create the wave and keep one side static, the same wave goes through the whole whip. Because whip narrows and the weight becomes less but the energy is the same so the height of the wave increases. Here is something else. It's not just one end moving in som of these cases but the speed increasing. So you add more energy. If we continue whit whip analogy. It is not just that you create the wave but you continue to move your arm and make the wave bigger.

I'm still not convinced. The floor tests would be convincing if the surface had very low drag on the chain. Otherwise you are just getting the Mould effect because of friction with the floor. In the final test, dropping the cord with lead weights, you are initially accelerating it downwards, thus creating a force imbalance. Seems Steve is rigging it with cups and plates, while you are rigging the experiments by using initial downward acceleration or ground friction. After watching both videos, I'm more confused on the topic than ever. Maybe if you could recreate your floor experiments but on a frictionless surface (like air-hockey table) could prove you right.

You have to impart that initial upward velocity and position of momentum at 16:00 because there is no mechanism in this ball chain example to force the chain to go up and build height, rather than reduce in height. Over the course of the test the height of the fountain decreases, like it does in your spaced horizontal tests, as there are losses and no opposing upward accelerating forces.

I haven't tested it, but wouldn't this be easily proven by describing the system with differential equations and look at the step response in the s - domain? The dynamics of the chain just looks to me like a classic overshooting step response settling over time. The chain's speed or momentum being too high and mechanical forces trying to dampen it to a target position. Or I could be talking out of my ass. Again, I haven't tested this. Either way I have to go with Team Mehdi on this one.

I'm with you, it has to be momentum. Just like cracking a whip. Part way through the vid I was thinking if you could get data to show the height of the loop was proportional to the velocity of the chain then that would prove it (momentum=M x V), but you did that with the black links at different heights! Point proven. And as you mentioned, I think the fact that the ball chain can rotate has a lot to do with it. It helps eliminate a lot of the resistance/inertia. Excellent work, for an electrical engineer... ;)

@ElectroBOOM, first of all, I'm team electronic engineers as well, so HIGH FIVE! . My question is, did the physicists or Mr Mould take into account the fact, that every link proves to be a slouch, or acts like a slack in the "pile" of chain which is being pulled out of the "container'? it may be possible, that chains with a really specific ratio of slack per link and mass per unit length of the chains, that decides how easily the chains are able to lift themselves up in a giant arc "over" the lip. My theory is on a similar line to yours, but I think, there's just one more thing that would make it feel complete. The effect is triggered when we pull down on the section of the chain outside the container. So, as the pieces or links of the chain which are at rest are actually "tugged" on to wake up and get moving, it causes an impulse on that link, thus, not really a continous "pulling" on the chain link, rather it kicks it into action, and so on and so forth. This theory also accounts for the fact, that there's only so much impulse a chain falling under the force of gravity can provide to lift a certain mass. Hence, heavier chain links, or longer chain links(not enough inertia) would lead to a smaller arc. On a side note, I've looked at the design of the ball chains, and there seems to be a link that's free to move inside the ball. Maybe that too adds up to the impulse per link? I think this is a solid thought as well.

This reminds me off an slinky toy (long flexible metal spring) . I had a large one and at the top of the stair it went slow and low and at the bottom fast and higher. Seeing that last piece off chain fly over would suggest it could repeat it self in multiple cups. As long that last piece of chain will fly over the edge off the next cup. So I am thinking why can a slinky walk stairs? So it would work with chain, rope, springs

Mehdi, one small thing. Stuff can practically have infinite accelleration. Think of a hammer hitting an anvil. With chains you'd get that effect when for instance you'd put lead weights on a flexible string like a fishing line.... The line moves at a (close to constant) speed and suddenly jerks up the weight going from standstill to moving in almost no time. Of course, the line will stretch a bit and the force will not be infiinte. But you can quite accurately predict what's going on by setting that time to zero, and assuming a certain delta-V across zero time.

you both make valid points and i'm all up for naming a constant after you. But if it where just the fact that there a loss of energy with the chain hitting the edge of the container, then the plastic ball chain with rope should exibit the same behaviour as the bathroom chain !?! also your 2d test doesn't cause an increase of "height" over time, now this might be down to friction of the ground or a lack of running speed (you not being able to match gravity). Perhaps you can build a winch with the same acceleration as gravity just to see if there is indeed a rise, and not just a constant arc?
