What would make these more interesting would be a real world application, at least written at the bottom of the screen, for each of those mechanisms, if they exist.
@@BlackOps2543x That was an obviously pointless mechanism, but the one that really left me scratching my head was the double impeller (shown in the thumbnail). Would it even work?
@@nagualdesign no it wouldn't since the right one is spinning in a direction that makes it useless. Also it's shaped like a scoop and not like something that pulls/pushes something through. It vaguely resembles a roots supercharger.
I agree - and they can't get stuck either (like the one at 1:30 would all the time)... However, I still find it inspiring. Those of us who know a little about mechanics will be able to fix most of the issues; those who do not know yet, will learn when they build the stuff. ;)
@@seekhimwithallyourheartand3358 the reality one can experience is a matter of perspective, influenced by ones pass experiences Its a very powerful thing capable of making someone seem like they are living a dream or if they are experiencing every stage of hell within their own lives You may go around spreading the word of your own god because from your own perspective its what led you to happiness its what set you free.. but without realizing this simple truth about perspectives you will cause others too suffer much like those who were purged in a religious mans crusade causing people to hate you changing their own perspective of religion into a vile disturbing lie that people default too whenever hardships lay before them or they may even see your gods as a fiendish being who created life then abandoned it watching it evolve from the sidelines someone who is most deserving of all the torment they have so graciously gave to us But its all a matter of perspective really and when those perspectives clash you will see a crusade in need when others will see a mad man blinded by his own truths Be careful with who you spread your word too someone might just say somthing that will make you think if your in the right or wrong :)
@@cameldesertship its somthing that if you think enough about its effects will show more and more only because of the way your thinking about it its confusing

1:45 Respect for the effort put in to color the interior and exterior parts of the gears differently. Makes a complicated sphere mechanism easier to understand.
Unfortunately most of them only exist as theoretical constructs. Once drag, gravity, resistance, stiction, common sense and every other force come in to play, most of these couldn't or wouldn't work under any sort of load. Some of these principles don't even appear to have a way of driving them even, and in the real world there are much simpler mechanisms that do the same work. It's cool to watch as a little "what if" distraction though.
@@nickmaclachlan5178 Such is true of the gear ball for instance which could at most be a sculpture, but many of these are proper mechanisms using known principles such as CV joints, geneva drives or four bar linkages.
Dan: "What are we doing today Arin?" Arin: *slams gears on the table* "We're gonna be demonstrating some mechanical principles!" Dan: "That sound neat!" Dan: "Wait, really?" (The grumps were literally the only thing I could think of during the whole video simply because of the music)
This music makes me think of a man frantically but excitedly throwing various toys and items onto a table while another man watches in both fear and excitement, awaiting what they might be doing that day
1:10-1:20 is the birfield joint used in many solid front axle Toyota trucks from the 70’s through 90’s. They may still be in use. Decent design, but they can’t take much abuse. A single u joint is stronger but speeds up and slows down twice through each rotation.
@@marog8536 In fact it's the opposite. This joint (CV or Constant Velocity Joint) is heavily used in vehicles with front wheel drive. The Universal Joint is pretty good but it has some limitations. In small constant angles they work well.
@Cernos I'm trying to make a lego 'great ball contraption' so I haven't got any diffculty visualizing it in use. I think it's an "in the engineers-eye" kind of thing. They could be used in any machine, and that's the shit
This is the sort of video that makes me wish that I could go through "Ingenious Mechanisms for Designers and Inventors" and use SolidWorks to animate every mechanism designed there in.
I believe I recognize something similar to the salt-water feed pump we had on the USS Fox, a 1200 steam propulsion boiler and turbine set up. The feed pump provided sea water to the evaporators.
0:26 I can see some huge potential for that mechanism with aquatic robots. That paddle-like motion can be sped up to make what would amount to a mechanical prawn. I could also see it gaining some literal traction on small boats as a way to make a vessel walk over sand bars. Definitely not a walking mechanism meant to support a lot of weight, but it could very well prove effective at digging into soft sand.
A water wheel would need to be retracted with a secondary mechanism. I thought about trying treads myself, but those would degrade even worse over time. Having a panel slide open like a plane's landing gear, and having this sort of leg motion would make it more compact and less susceptible to damage over time. Granted, it still needs a pump to get the water out of that compartment, but there won't be as many moving parts for water to cling to and degrade.
@@WarChallenger just drive on the edges of the water weel. and when its in the water its like a river paddle steemer, no retracting required. there is also a company that makes electric drive conversion kits for dingys. so weels deploy and you can drive the dinghy like a car up onto the beach or sand bar or whatever.
Never knew things like that already existed. I know that snowmobiles are oddly good on the water, so maybe with the right waterproofing, a tread system could also be used. I just find the mechanism in the video fascinating, since it perfectly mimics the paddling motion of marine creatures like shrimp. There's gotta be a great application for that mechanism somewhere.
And a source of info for DIY'er backyard mechanics. I know many have no real purpose and unfeasible, but the principals of the movement I need to do, satisfies my curiosity.
The first mechanism could easily invert one of the arms from the horizontal positions. It would in fact be much better to just use 3 arms. But not as aesthetic I suppose.
Notwithstanding the scores of branches of engineering now in vogue, mechanical engineering is the true engineering. From ancient times, it has worked for the benefit of mankind. Videos which explain the commonly used mechanical devices such as cams, flywheel, differential gears, rack and pinion, gears, planetary gears, levers, principles of hydraulics and pneumatics would be of great educational value.
As a complete ignorant, I am totally amazed by videos like this, and the incredible inventive by engineers. The amount of things that I use daily, and I take for granted, that have got brilliant ideas and developments in their insides... To me, you engineers are wizards. I wish I had your IQ, because you build the world and make our lives easier and fun.
Yeah... I get the feeling some of these mechanisms might have been dreamed up by people who never have and probably never will actually work on, let alone make, any physical machine. Or perhaps that mechanism is only intended to mix liquids rather than actually pump any...
I've been wondering wtf that's for. Its function is totally symmetrical so nothing is being pumped. And I noticed the light blue coloring doesn't take up any 3D space so I think it's just a confusing color choice that looks like water but wasn't meant to actually imply any. I concluded that it's a way to have two gears shoved into a close juxtaposition without having to shrink their maximum diameter or nudge one onto a different plane. I can't imagine a reason anyone would need to do that though so idk. Best guess is mixing something, yeah
What would be cool for all of these renders would be to see a 2D or in appropriate cases a 3D plot of the displacements vs time. So velocity curves and then a 2nd derivative plot showing obviously acceleration. You could put it below or find some cooler way of mapping it in the video. Also, would be great to see force at the output and the other components given the input. that could be unit less. This could be graphed as well of course. To complete the training the typical use cases, failure points, areas where wear occurs preferentially and how these issues are addressed in real life, with say alternative mechanisms that achieve the same result. Would also be cool to the see the names of these mechanisms, where they are most often used or have been used and I almost forgot, labeling of the driven portion and the output. Maybe initially showing the portions that have to be fixed or constrained and then it could be exploded away during the animation, or maybe wireframe or see through vs shaded. Equations for the statics and mechanics involved or sources for that info in a reference section would also be cool. This would make it next level for mechanical engineering students. While I am dreaming, it would be cool to see real-time stress and heat maps with coloration on the pieces. Maybe your program has finite element analysis and can spit that out? Some parts of the videos go by a bit too quickly, so chapter markers would be awesome. STL files would a,so be so cool so that the pieces could printed and then a student could follow along by making their own. Holding these in one’s hands would add that extra element that would make the educational value even more powerful. These videos are such an awesome idea. Excellent work!
Flash back to Design of Machines and Mechanisms: "Parameterize the path of point A on link 2" On more than a few of these I was trying to imagine the path traced by different points on different parts of the mechanism...
It's 3am... Watching these mesmerizing visuals paired with the calming music... I feel like I'm ascending into a higher plane through sleep deprivation and bedtime revenge procrastination...
We must master in Geometry, Algebra and Trigonometry. These are basic for Mechanical Engineering and also get you through Aptitude test easily. Your focus and 4th level design and result work up in your mind easily.
Reminds me of machinery in the late 1800's and up to WWII. Some one should do a 3D animated video of old industrial machine mechanics operating in slow motion. From steam locomotives to sewing machines to old clock towers.
I agree. That is what they were created & designed for; to solve a particular problem. Whether it was to drive a circular wheel of a steam engine or to operate a weaving machine up and down. Necessity is the mother of invention. But once we have solved the problem it can then be applied to other uses.
Yes! This video immediately made me think of watching the huge steam-powered piston engines on the sea-going paddle steamer The Waverley, when we used to go “doon the water” about 60 years ago. And my grandmother’s Singer treadle sewing machine ☺️.
Hey, pretty cool stuff, what software do you use to render these animations? I'm just starting to learn freCAD, I wish I could design things as cool as these. More motivation to keep learning, thanks!
Weirdest choice of a blatantly copied comment that I've ever seen. Someone posted this the day before you, identical right down to the typo. Why? Why the hell bother copying it? What a weird decision

I came here to point out just how useless that 'pump' is. It's nothing more than a rendered circle jerk, any fluid in it wouldn't usefully move, and if it's supposed to extract rotational energy fr flow, well it doesn't even seal well and thus useless for that too.
1:40 If each gear is a node in a graph and adjacent gears are connected, the gears can rotate only if the graph is bipartite, which means every node can be given one of two colors with no adjacent nodes having the same color.
