If this channel has taught me anything, it’s that clockmakers are essentially wizards
-
This is quite possibly the only channel where they introduced voiceover and everyone preferred no talking at all. Truly a special channel.
-
The 1:1 ratio experiment was super interesting. It shows the storage of energy in a mechanical form and the tolerance of the mechanism. You could equate it to reaching the top of a hill. You build a tension of energy climbing up a hill, and that energy is rapidly released by means of gravity going down the other side.
-
The delay in the last experiment was fascinating! It's like a capacitor for torque!
-
Great content, but I preferred no voice over the robot one.
-
I would be curious to see experiments on loss of torque transmitted through a universal joint (the LEGO piece and possibly some MOC U-Joints) at different angles.
-
The Oscillating Tire is well known in the belt industry. Basically the raised center of the wheel makes more contact, so when the tire steers off to one side the friction pulls it back to center.
-
0:30 The oscillating tire is adorable.
-
I had that idea for the 1:GOOGOL but then I remembered about the insane amounts of torque required to do that. General rule of thumb is that as the gear reduction increases, so too does the torque, this is why vehicles like farm tractors can inch forward at idle if you release the clutch at lower gears.
-
excellent video as always, I just personally prefer the videos without any voice over, same charisma as in the original lego games!
-
At 1:50 how awesome was that delay from backlash. Reminds me of a train engineer I met and he was telling me about mile long trains he’s pulled and how careful you had to be when speeding up and slowing down because of slack. You could potentially snap a coupler or worse
-
I legit have thought about that first concept for over 15 years and have always wanted to try it but never had the resources. You have earned a very strong subscriber.
-
still waiting on the wall climber that uses a grappling hook, that would be awesome!
-
1:22 That's so cool! It's almost like a physical capacitor or something. Probably a bad comparison, but y'all can probably see my point.
-
I have seen snapped pins that seemed to shatter and I always thought, why didn't they make them out of a more ductile steel/temper. This video actually showed how any elastic slack in the drive/cogs actually destroys efficiency and why harder less elastic metal is better.
-
That's a lot of experiments in a short time and no BS, subbed!
-
0:30 This is the "crowned pulley" effect. There are lego videos that explain it on YouTube. It works with the tyre because the centrifugal force expands it and it only touches the rim from one spot at a time.
-
2:00 insane how like zero movement but torque is able to produce so much energy!
-
I love how open you are to requests, keep up the good work bud
-
2:08 the problem seems to be that the two right ones aren't fully connected to each other.
