20 Mechanical Principles combined in a Useless Lego Machine

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

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

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

With the world becoming more digitised and discrete, it's nice to see some good old-fashioned analogue mechanical devices.

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

Brilliant! Thanks to LEGO designers, engineers, and inventors too!

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!

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.

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.

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.

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!

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!

6:42 this is how real generators should look like

LOVE THIS VIDEO! I've watched it many times. Like those SpaceX Falcon 9 booster landings, this never gets old.

Think about how valuable this demonstration would have been a couple centuries ago. So many inventions/discoveries in one place!

If this were to be an actual Lego set, I would 100% buy it.

1 min in and you have me fascinated by the trusting machines, one ball, two ball, now I see a ball and box thrusting machine.

Fascinating video. Should be a must watch for all aspiring engineers of any age.
