20 Mechanical Principles combined in a Useless Lego Machine

Finally, YouTube doesn't think you're a kids channel anymore.

I would like to point out this machine is not useless: its use is demonstrating 20 mechanical principles 👍

Netflix : Are you still watching ? Someone son : Slider-Crank linkage

I like how all the individual mechanisms all have their own purpose that shows off what they're designed to do, like: - The CV joint alows for freedom of movement without altering speed - The bevel gears allow for a 90 degree change of direction for the power to flow - The lambda linkage - The gearbox changes polarity

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!

This should be a legit Lego kit for mechanical engineering and industrial design students! Its pure art...

-Hey, where did you learn about these mechanisms from? I thought you went to Art School? -Uhhhh....

When u want to be an engineer but u dont wanna leave ur childhood :

This looks so old school, like from the industrial revolution. The machine is only missing a governor spinning around, and perhaps one of those sad-looking steam whistles 😅 Great video!

With 20 years of industrial maintenance under my belt I can say with 100% certainty and confidence that I've worked on machines with far less lubrication than this one.

Love messing with gear set ups! Once used a worm gear to lift and lower a 2.5 ft swing arm on a Lego build, it was awesome!

I imagine Lego could make quite a bit of money selling "Mechanical Principle Sets", both as massive combined ones to schools, and as individual sets to enterprising engineering students. Having a physical model, especially one you can modularly combine with others, would have helped me ALOT in high school and college.

Feels like one of those things where you show this to a kid and it'll set him on a path to becoming a mechanical engineer for the rest of his life

Amazing construction, and fascinating how each component works in union as part of the overall machine. Something like this would be great to teach people at schools, to be inspiring for future engineers.

Fascinating, and the machine fully constructed is brilliant 👏

Other than being the most INEFFICIENT power transmission device, it is also the most interesting that I've seen. Great work!

Each one of these was a break through in science for the time. Hard to imagine living before mechanical life.

Bravo! I loved the combined masterpiece at the end of everything working together.

I just want to say thank you because I used a part of your video in a video I created it for my client
