I decided to check how effective the popular mechanical principles of Lego mechanics are. Tested with high RPM and high-torque mechanisms to determine which joints are more durable. I hope you will like to know it.

I have verified that a tensioned chain works better, thanks for the advice.😊

can u do a collab wid td brick please

@logtrimmer Год назад

I feel like the chain drive might have worked better lifting if the chain was not loose.

@stopmotiondoctors Год назад

Same

@Moriarti Год назад

a chain stabilizer is required

@theUnitedindia56 Год назад

Yes you are right

@kbeightyseven1783 Год назад

The chain needs tensioning correctly

@AtomicA7 Год назад

True

@leviparrow1532 Год назад

i think the chain and belt drive wouldve done alot better on the rpm test it better tensioned

@AtomicA7 Год назад

If the lifting rig was more rigid and strong and didn’t bend most of those failed ones would have lifted more also you said one failed but it failed because the lego persons head came off because of the centrifugal gs it was experiencing

@AtomicA7 Год назад

And others failed because they weren’t secure properly

@AtomicA7 Год назад

Also the chain one even though u did reinforce the structure the chain was to loose

@legoislandstuff8773 Год назад

he knows gears just not structure

@lukasrockwell1935 Год назад

The gear drive should have been the best if he fixed his stand

@Gregzenegair Год назад

Yeah, the test of some are not optimised, some times against a bit more weight, tweaking , you would win reliability

@poelmeister Год назад

That chain drive test wasn’t fair. The chains was too loose. That’s no way to test its strengths. You think the timing chain in a car would slack like that?

@SWellWellWell Год назад

And this can affect the speed?

@user-bk2bk9zh8q Год назад

@@SWellWellWell, not on such a test stand. But if the shafts are fixed more well, then at a higher speed the chain will start to fly off without a better tension. And it will not slip as in the maximum load test.

@grande1900 Год назад

I think the thing that needed the most strength was the stand lol

@comradealex85 Год назад

The rig and its insecure mounting are detrimentally affecting the results. The test rig in itself should be the strongest component to a test.

@marcosacceleronhotwheels2806 Год назад

3:01 is no one going to talk about how the lego man head simply poped off due to how fast he was spinning

@joaovictorbombonatodepaula3133 10 месяцев назад

Bro was straight decaptaded

@DrEngine Год назад

Lego allows for many mechanical principles. I decided to check how effective they are. ️ Are there any suggestions about tests?

@DrMindstorms Год назад

I would make the structure for pulling the weights a bit stronger, therefore the mechs can be pushed more to their limits

@DrMindstorms Год назад

And ofc, excellent video!😁

@xyxxyx4883 Год назад

it would be great if you wolud just make as high torque as possible lifting

@user-bk2bk9zh8q Год назад

I think that with a stronger fastening of the parts of the 4,5,6 mechanisms, they would be more effective. And probably the 3rd.

@nitroboom1282 Год назад

Could you try the chains facing outwards? It really helps performance

@Xaxationlorex Год назад

Test rig needs some major reinforcement ,lots of straight runs with no cross bracing. Chain was also super lose with too many extra links. Some resigns and another test seem in order.

@edwintorres4224 Год назад

I feel like the test was unfairly made.

@unibrandon Год назад

it was unfair the chain link was way to lose

@hardstyle4evajarhead Год назад

When the engine and gearbox side flipped under the weight i lost it hahahaha! love it!!

@DrEngine Год назад

Glad you like it ☺️

@nicolethetigersharklatex7858 Год назад

Just love how it failed and passed at the same speed

@Merecir Год назад

I am sure I must be the first one to mention this, but the chain being so loose made the test unfair.

@xxforDJofficial Год назад

Try tightening the chain link, that makes it stronger

@janaepeso7417 Год назад

The gears look like they are about to break the speed force of DC lmao

@bdlc9952 Год назад

the chain drive is better than the belt drive because the belt relies entirely on friction while the chain drive has a hook like design

@DroidzandBrix Год назад

That gear drive could have gone much faster if you put another beam in front of the gears

@crazynachos4230 Год назад

Yet it was there for the actual lifting test

@JamesTDG Год назад

5:43 that doesn't look like an issue with the chain and more an issue with you adequately anchoring the gear

@okipullup9036 Год назад

I'm pretty sure it would be inadequately

@user-no3vf9ry8u Год назад

I bet the structure will break or not. hahaha. Emotional!!!

@martinteece8983 Год назад

For the higher test weights would it not been a more fair test to Stableise the structure with braces

@kasuraga Год назад

The chain and belt drive tests should be redone. They didn't nearly have enough tension on them to be effective.

@Circ Год назад

The belt drive might have done better speed wise if it had a convex roller on one end to help center the bands. The concave indentation wasn't enough, physics

@SpeedCube2 6 месяцев назад

It seems to me that bevel gears is very underestimated, because if the structure is made more durable, it will be able to pull out more revolutions per minute

@ZephytheDragon Год назад

The CV joint would've reached a much higher speed without the unbalanced weight on the end of it....

@mattimotion Год назад

I love these Lego Gym episodes

@DrEngine Год назад

Thanks 👍 It was fun to make!

@user-kv1xd7ly5e 5 месяцев назад

idk to say but tension plays a big role in the chain. i have tried this myself

@lupinzwolf98 Год назад

The chain being tighter might have improved proformace

@DarkVoidIII Год назад

Dr. Engine should call in his doppelgänger Dr. Engineer. This rig was interesting, but needed some serious structural improvements! I tested LEGO pneumatics when I was younger, it could lift a few pounds. Most models needed sufficient weight in the body though or it would topple too easily.

@blackholetree Год назад

Ok but the subtle detail that the lego minifigure's expression changes are being spun the first time is golden

@TessaAndrews Год назад

it's kinda funny to see the pulling mechanism just cripple up.

@kevtheoggamer6672 Год назад

At least the mechanisms breaking looks satisfying

@nyscersul42 Год назад

You need a diagonal brace off the pulley mount to the drive system... no flex then, all your system is expecting that one not reinforced point next to the drive pulley can handle all the stress.

@simon2cool4u Год назад

On the gear drive, It was unfair because the gear fell of because it was not secured properly, so you said it failed.

@necrovarius225 Год назад

RPM on the belt drive wasn't fair. The belt drive didn't fail, the minifig did.

@SwatDood-qk6hs 10 месяцев назад

Poor Lego guy, before the first test, he was confident. After the first experiment, he was scared!

@carcollecter98 6 месяцев назад

You ever wonder why chains are, you know, tightened? This is why. Your test was done incorrectly because the chain was horrifically loose. If that chain was actually tight like its supposed to be, then it wouldn't skip the teeth on the gears, and it would perform much better. Maybe give the chain another chance by actually doing it right.

@ac_dcpol 19 дней назад

Love this channel ♥️

@JacobL228 Год назад

Your chain drive looked way too lose. You may want to take off a link or two and retest with a tighter fit. Also, the gears on your gear drive flew off because they were exposed on one side. I don't think that wound have happened if there was a liftarm element on both sides.

@unibrandon Год назад

on the lift test there was one

@carbonphantom1 Год назад

Did that chain dirty as heck

@samurottstudios2066 Год назад

Totally could've tightened that chain

@anonymous-mj8wb Год назад

chain was to loose. it needed a tensioner. then try again.

@delavanty Год назад

I'd also recommend using the locking caps Infront Of the gears on the skin colored gears they would stay better

@fry22wr Год назад

@Yora21 Год назад

How is the little guy mounted to the wheel? It spun so hard his head flew off!

@amycosmicpuppy Год назад

Lol, with the gear drive, everything except the gear drive was breaking

@Taijitu527 Год назад

1:14 speed is so high it looks like is static on place

@delavanty Год назад

The chain drive could have been a bit tighter it was looser than my father's belt after Thanksgiving

@LunarcomplexMain Год назад

Everything seemed fine up until that loose chain, why on earth would there be so much effort into this just to lead into using a loose chain?

@liammcquillan6851 Год назад

chain and belt drive should have had tenstioners

@derekhale7948 Год назад

The gear drive might be the easiest to fix

@Rattlesnake3170 Год назад

Uh man that Tower there looks like it's gonna break

@alfianfahmi5430 Год назад

Bruh, those chain belts are loose as hell. No wonder they slipped everytime 🗿

@phalinangel Год назад

Tighten the chain up!!!!

@robertsummers3386 Год назад

Maybe don't have a loose chain on the chain drive, and it'll work better.

@VIP-ry6vv Год назад

Dat chain tension tho.

@athanbelo6369 Год назад

Chain drive was a joke. Take a link out. No one runs a chain that loose

@toygarage-artofplay9798 Год назад

Awesome, how you calculated ?? ❤

@MaccasAdventures223 Год назад

also when the slots on the chain face outwards it works better

@karnyamaw Год назад

Can you test adding a proppeller

@KolejowySzynszyl901 Год назад

Dr. Engine. I have a question. Why chain drive pass before reinforcement 500g and after reinforcement you said it didn't pass?

@williamhodges7957 Год назад

I feel bad for all of those technis pins

@KrystineChristenson Год назад

Yeah you definitely need to make a better rig for the lifting test

@DrEngine Год назад

Working on it!

@Mrskarr3524 Год назад

I bet the gear drive could have done 2kg

@barrianic4 Год назад

1.5kg broke part of the lifting wheels at the top

@dz-abouttechnique1849 Год назад

Cool!

@tyreewadsworth1593 Год назад

You got to tension the chain more

@gladiatorone9023 Год назад

NEED! MORE! POWEEEEER!!!

@thespartanamongus1121 Год назад

The chain drive is not set up properly. You can easily take two, maybe three links off of the chain and it'll work better because it's taut and not loose.

@nukem9504 Год назад

2:55 - 3:04 It seems the Lego tester lost its head over the test results!

@Bubbibjoern Год назад

You made the chain way too long, it would not have failed that easily.

@stonerscancatch Год назад

You put the chain on upside down

@brodygamer83 Год назад

6:48 bruh tighten the chain

@youraveragemx9492 Год назад

Need to tighten chain

@kaikevargas7387 Год назад

The chain was too loose

@marktegrotenhuis Год назад

Almost all of these failed because of structural strength/durability, not because the mechanism itself failed. A true mechanical fail would be skipping teeth, breaking gears, breaking chain, twisted rods and breaking rope.
