First time I saw a worm gear I was around ten. My grandfather had built me a tree house. But being a machinist, he didn't stop there. He figured I might want an elevator for my tree house. Mom was terrified of the idea of the elevator breaking and me falling to my death. So Grandpa made one with a worm gear. It might have been a near record one being forty feet high, the height of our tree house. Wonderful view. Grandpa also built a roller coaster next to the tree house and a lot of things way too cool for my parent's comfort like build his own electric power plant by stealing electricity from radio waves so we had lights in the tree house, not to mention a working radio that didn't run on batteries and you didn't need to plug in and a mechanical battery that would save mechanical energy when the wind blew and then when it was hot and no wind you would flip a switch and you had a fan that ran for hours.

This took me way back in time to 1966 when I was in fourth grade and curious about mechanical linkages. My dad and I were sitting in a restaurant on rotating bar stools with round seats, waiting for a take-out pizza. He used the stools to show me how forces are transmitted by gears and wheels. First sitting right next to each other ("When I spin this way, which way do YOU spin?") then with one or two idlers between us, spinning me around fast when I was correct. We were laughing and having a great time together and I learned from it in a way that stuck with me forever. This demonstration on your channel today gave me some wonderful happy memories of my dad. Thank you!

[@XSniper74184]

Well the issue there is almost of these are just variations of the sams idea: changing one kind of motion into another or transporting it. They're good for a specific purpose but not much outside of that. Like the most important bit to people who didn't know about this is simply the gears and their mechanical advantage. Just hook a few gears up to something you can make spin like a windmill or water wheel, and now you've got a drive for your machine. Use it to grind grain or spin a saw blade or pump bellows. The leap not explained here that would be huge is the power source. Not needing to rely on the wind or water for drive was what made the steam power huge. We already had all the gears and pulleys for a long time, but being able to power them wherever we wanted and scale up that power in was the part that made the industrial revolution happen.

Fun fact: possibly one of the most noteworthy uses of the rack and pinion principle is on the Snowdon Mountain Railway, where engines specifically designed to tackle the steep gradient ferry passengers to and from the summit! Their wheels are built with pinions, which fit into the rack built into the rail! Other modifications, such as slanting the boiler so that the water would remain level on the gradient and building the cylinders back to front were made so that the engines could tackle the mountain! It’s truly fascinating stuff! Edit: I am aware of other uses of the rack and pinion principle, hence why I said “possibly one of the most” as opposed to “objectively the most!”

I love this! I'm NOT a big fan of Lego "kits" that build just one thing but if it can put together to demonstrate all these (that many wouldn't understand or think of) to build something is a big exception! None of the Legos I had as a kid came as a "build-this-thing-according-to-instructions" kit... just a big box of several assorted pieces and a lot of imagination and we came up with lots of new toys & gadgets. (I used to carry all my random pieces [about 3 assorted boxes-worth] in a big, paper grocery bag. And nothing got built just for display. They all came apart for another new project.)

[@criran]

Sort of, but not really. Some of those machines do nothing but spin and create extra work for the motor, ultimately resulting in a significant loss of work. In a Rube Goldberg, each segment of the machine performs a specific task which ends with the start of a new segment while ultimately striving to achieve a very simple function in a convoluted way. This machine performs a simple task (spin the Viking angel figure) but wastes a lot of work on segments that don't contribute to the ultimate goal. Frankly, I'm kind of surprised the motor didn't stall.

As a child Lego was my only toy. I didn't have many, but I had old ones and some techniques. I turned out to be very good at the age of 12 at repairing things, fiddling with bicycles, fixing 2 stroke engines and understood easily the mechanics while my peers were baffled. That can't be a coincidence. IMO Lego offers more than many other toys, helps logical thinking, manual precision, learning through trial and error and many other things that other toys don't offer.

My sister like 5. Slider-Crank linkage

[@DrWhom]

Yes, many of these linkages have excessive friction, wear and tear as their drawbacks, which means that in practical application they must _always_ be offset by the additional degrees of freedom of movement they offer. This is why I expected some of the movement to be directed backward to actuate (move about) the fixtures of some of these linkages. So I am rather disappointed. He missed an opportunity to demonstrate just why these solutions exist.
