Regarding the backpack: when you study vibrations in engineering, you learn that there's a specific frequency in which you can vibrate a spring-mass system where it will not transfer that movement to the mass. That's why there's a "sweet spot", and all the people in the commercials were running with that sweet spot frequency, where the backpack barely moved even while they were running (i.e. the movement of the person was barely transfered to the backpack). This depends on the spring constant of the springs used, and on the mass of the system (the backpack and whatever's inside it). So if Mark were to put more weight in the backpack, he'd have to find a different running frequency in order to get the same effect. Thanks for sharing all these cool experiments and knowledge with us, Mark! You're awesome!

@marzipancutter8144 2 ай бұрын

Now I'm wondering if it was possible to adjust the stiffness of the spring on the fly. It might be completely impossible to do this to a degree where it can be controlled electronically in real time, but it's a fun thought to imagine the backpack changing its spring constant to stay in the sweet spot for any given mass and walking speed.

@jarsky 2 ай бұрын

@@marzipancutter8144 You could probably leverage automotive engineering concepts for this rather than electronically. If you look at suspension, there are progressive springs which as the spring compresses changes the resonant frequency. You can also get dual rate springs, where you have a main spring of one size/rate, and another spring of another below it on the same strut. That would be ideal for riding on the main spring and retaining resonance over the flat, and the shorter stiffer spring for taking the big dips, and again should stop it from falling into another phase frequency. But of course you would still have the issue of the frequency being dependant on the weight of the pack.

That backpack reminded me, if you walk with your drink, the equal frequency of your steps is building up waves in the mug, so ultimately you spill it. I do my "silly walk" with unevenly distributed steps and it truly helps make my way without spillage. With that walk I basically create waves that go against the waves I already created in the mug, mimicking how active noise cancelling works in ANC headphones.

@@liliowen2132by rope thing, I assume you mean number five, the belt around the Earth. That's actually simple math, the problem is that we imagine it takes a lot more length to do a thing that actually requires very little. You can simulate this for yourself, take a length of rope or string, hold it against a wall with both thumbs. Take a look at how very little you need to move your thumbs towards each other to make a significant bend in the rope.

It's not like pulling yourself up by pulling on your hair. The energy is contained within the system. Blowing your own sail has energy escaping the system, just that most are going sideways with a little going backwards, hence the inefficiency.

Mark, for the sail and the fan, what if you put the fan blowing from the side and the sail in a beam reach, then adding a counterweight on the other side? This way, the air molecules bouncing at an angle off the fan would push the boat forward and the counterweight keeps the boat balanced.

Blowing your own sail, while wildly inefficient, does actually work with a traditional CURVED sail. The curve captures the air from the fan and redirects some of it backwards, which provides a small amount of net thrust in the opposite direction of the fan. Love the channel, but I would really appreciate Mark revisiting and clarifying this

@erwtgfan3877 Ай бұрын

He should have mentioned the reverse thrust on a jet engine

@MrGamelover23 Ай бұрын

He literally did it on a real boat with curved sails and nothing happened?

@cuddlestsq2730 Ай бұрын

@@MrGamelover23Might be because of the positioning of the fan and its size. The fan was much lower than the sail, so the air would be redirected more upward, and perhaps the since the fan was close in size to the sail the air flow from the fan would disrupt the redirected air from the sail.
