so had to look around and find the other part of the episode, which is 2 years older than the one just posted by discovery australia.
Yea the timing is super strange
Very disappointed in the lack of perseverance.
Yeah, "didn't work first try, lets blow it up"
All available Perseverance has been sent to Mars...
1:20 Well I'm not a rocket scientist like everyone else there.......but the mud might have something to do with it
Rocket scientist throw money at the problem, People solve the problem. Idk I love Adam and his shows etc. But good god is he a simple minded man.
Nah the mud doesn't really matter, the problem is the energy transfer from the flywheel to the actual wheels. They tried to use brakes like a clutch, brakes are literally designed to dissipate mechanical energy as heat not transfer it like a clutch. Like they said if it clamped a lot faster it might have worked better, but really they just needed a faster stronger clutch mechanism.
@@Kanglar Try running in mud and then asphalt......let me know which requires less effort.....go ahead....I'll wait!
@@williamskrainski8407 but that's beside the point, it wasn't just that it stopped or didn't go to the maximum possible distance.
The problem was it didn't go forward at all, cause the brakes didn't work well enough to transfer the energy.
Sure they could test it on asphalt and it might look better, but the underlying problem of enormous energy loss would still be there and it would not work sufficiently well
They were losing energy in the form of heat due to their improv clutch system sliding. Their clutch system was made of a device that specializes in turning kinetic energy into heat, extremely efficiently. That device is called breaks.
Think of the big job the breaks on your car has. It converts kinetic energy into heat...which gets dissapated. There's a ton of energy stored in a car when it's travelling 60 miles an hour. Yet, your car's breaking system can turn that energy into heat effortlessly and quickly.
This is how they lost their energy.
You can do this electronically too. Just connect a dynamo to your wheels and then connect resistors to the dynamo...then dissapate the heat from the resistors. Some trains break this way. And you might know, trains built up a lot of kinetic energy.
They should have used a method that generates less heat.
Only one attempt seems like such a waste. I would have kept trying. Maybe an idea similar to how the saw stop mechanism works, but scaled up (alot), would have been better. Or a clutch brake with teeth with a ridiculously heavy spring held back till needed and with groves embedded in the flywheel.
Hell maybe a high voltage arc to weld the flywheel shaft to the body. Or firing a tapered cylindrical cup onto a shaft might work.
Weld wouldn't work, it would just shear the hot steel
@@seanlanders4180 other options may be viable.
@@ITpanda definitely, tons of viable options. Disposable clutch would be the best IMO
Weird that they didn't try again with better breaks
I guess it was the money and deadlines
Maybe meet in the middle and have the flywheels acting as the gyroscope to keep it steady and use rockets as propulsion
The point of the test was how to build it WITHOUT rockets
@@jamesguth5511 Sure, they wanted to do it without rockets because it was unstable and they couldn't get them to fire simultaneously. Use the flywheel to provide stability (won't need the brake) and the rockets to provide thrust (don't need to fire simultaneously).
brakes should have been radially mounted instead of axial. leverage 101.
How to make content. That didnt work like we wanted it to? Blow it up
Why not fix it first?
This test didnt fail on accident. The people working on this were way too smart to let that happen. This was deliberately sapped so as to ensure nobody viewing got any ideas as to what exactly could be accomplished with this weapon. Think about it. Its would not be hard tonsource the materials and build this yourself without drawing any attention whatsoever and something like this has the potential to be MASSIVELY destructive if utilized correctly.
Everyone complaining they didn't fix it.. they're on a budget, a TV budget, not an engineering budget lol
Honestly, the solution is so simple..... a single smaller wheel between the two larger wheels to which the rockets are mounted. Single plane propulsion no torque steering issues and no worry about when the rockets ignite. You could even set up a second set of rockets to fire on a delay to increase range.
Prof wells, thats genious.
The mud most definitely had an impact. Spend a summer as a farm hand driving tractors in fields. When you hit mud, you know you hit mud.
From the engineering perspective, torque is the propensity of a linear force to cause motion. It’s F x r, aka force multiplied by the radius, aka foot-pounds of torque. If you double the radius, you double the torque. This is why mechanics use a cheater bad with wrenches when trying to unstick a rusted bolt.
So, this is how the mud affected the experiment. Even though the mud force itself is deceptively small, what matters MORE is the distance from the axis of rotation. The force of mud acts counter to the force of the brakes, which are VERY close to the axis of rotation. So the brakes exert their force close the axis, the mud exerts its force far from the axis. The result? Almost certainly the majority of the flywheel energy converted into heat, and when brakes get too hot, they no longer work (hence truck escape ramps on steep hills). Watch a truck plow into one of those escape ramps and you will see the awesome energy-absorbing potential of soft earth.
So, to sum it up:
1. Soft earth demonstrably absorbs enormous amounts of energy.
2. The tremendous difference in radius of the brakes and the mud is plenty to counteract each other.
3. Brakes likely heated to their energy saturation point faster than calculated, causing a slowdown in the transfer of energy.
In a previous life, I was a physics teacher.
I’m not claiming the mud was the absolute issue, I am saying it MOST DEFINITELY contributed in a material and substantial way.
It would be hard to calculate the resistance on the wheel from the mud as well....
Guarantee that landowner was f*ing pissed they traded the field
Forget the brakes/clutch/transfer of power all together. Weld it so the flywheels are locked to the wheels (and balanced, of course). Raise it up on a collapsable stand, power up to an ungodly speed, disengage the motor, drop the stand, and watch it go.
You probably assumed a low friction rolling surface......like pavement. That mucky field would have presented much, much more resistance...
Cool video
The radius on the wheels is too much. As we know F=mv^2/r so for energy transfer, if the radius is twice as large, the force is half. (Basically, there wasn't enough leverage)
Just gonna say, to everyone saying they should've tried again, they really didn't have the time to try again with this show. Unlike mythbusters, they didn't have the time or resources. If the problem with it was something they could fix there they probably would've done it again. However, since the breaks were the problem, they would need to remove the breaks and get new ones that are much stronger and more efficient in their transference of energy. This is something that they just didn't have time for. Plus, this show wasn't really about testing myths, it was about Adam building fun things hoping they work and if they don't it doesn't really matter. But yeah, Adam did say he wants to do a Re-Do of the Wheel of Death so I'm sure they will when they get the chance.
LOL, if you had moved the calipers onto the outer edge of the flywheel it probably would have worked better, you just smoked the brakes with the flywheel having more force than the brakes on the rotors could cope with.
yeah and these guys are supposed to be "smart"
Absolutely right
get some Brembos on this baby
"Friction - she's a bitch." It turns out that a lack of it can be a real problem too.
Blowing it up for "entertainment value" after a failure seems so cheap and a cop out to our instant gratification society today...
Yeah this thing would not have changed the course of WWII lmao
"This is an unusual experience for me"
Adam NASA meets Adam SpaceX
The failure ritual is exactly the same for both sides.
So just blow it up, kids.
Best possible plan B there is.
Clickbait much....
Well it's there so if anything you click bated me its from ww1 maybe it's ment to do something like blow up but it might be old no offense
Not clickbait at all, that IS what a panjandrum is, its a REAL thing back in WW2 to roll over german defenses and blow up the walls and bunkers at the end of the beach. Just because the test didnt go right, doednt mean the description of the real life weapon was false... they did indeed test a WW2 weapon
Oh... it was just some faulty breaks...
Blow it up.
y u no move forward?
I wonder if they would try the steam cannon again, but before they try they need to talk with me. When myth busters tried they failed to take into account a few things that Archimedes would have done. 1. Copyright was not a thing.. ( misrepresented drawings) 2. Sloppy welding/Cutting. Inadequate holding force on the projectile. To name the glaring issues.
What if you had the “rockets” on the sides/ends of the axel instead of the the wheels for the initial launch and the momentum gets the fly wheel spinning somehow that keeps it moving after you cut the rocket power
Those are some small ass fly wheels.... My brigs has heavier smh... Damn city boys....
Why connect the rockets to the wheel and not the superstructure?
Mud, nature great equaliser.
The reason this does not work is because angular momentum is not conserved. Angular energy is conserved. We have been making a stupid mistake.
Wait. DC's deathwheels were real?
Now you know what the idea was based off of.
I thought some sort of "wunderwaffe"
So fresh but not like mine
半トルク式パンジャンか...
Mud soft ground takes alot of the power away quickly ... Duh
Billions ???
All they had to do was a gofundme for a few brake parts and a week later this would have been a magnificent showing. Oof
After finding the video from 6 days ago, this conclusion is incredibly disappointing. Explosions are cool but really? I had higher expectations.
Should have used drum brakes
I was thinking about rather using several disc brake calipers on the edges of the rotors... they already have the rotors, and they seem to be about as thick as your average car's disc brake rotor
I don't think drumbreaks would have made a difference.
They should not have used breaks to begin with. Breaks are designed to suck out kinetic energy and turn it into heat....and it does this extremely efficiently.
It's how your 3000+ pound car manages to get rid of its kinetic energy like it's nothing, every time you use the breaks.
Lack of perseverance from the men. Expectations of clutch from brake assembly, ignoring friction/traction effects while driving the unit into the mud.. the list goes on could've tried with some iterations successful launch wasn't so difficult. It's simple theoretical physics, without realistic considerations !
Gyro
Shit !
obvious ... structurally unsound.
Way to give up
disappointing
Lame
The math was wrong! Think about an ice skater ⛸ and rotating motion. An ice skater spinning with there arms out will speed up as they pull them in toward there center of mass. The same thing happens in the opposite direction when they extend there arms outward it will cause them to slow down. And this is what was not accounted for in the calculations. I would love to work at nasa if you will have me.
What a dumb, disappointing end.
This is just depressing. Why do you bother?
You should make free electrical energy by fly wheel
Is this possible? Plz anybody tell me bcz youtube lot off videos but they are fake
You can only get as much energy out of a flywheel as you put into it
@@MorzenMebs everybody know this
But free energy possible??
Did u watch videos?
@@zainpakistan1797 there is no free energy however with a good gearing system you can get a flywheel up to amazing rotational velocities using just human muscle power and then the energy can be bled off slowly to run a generator. So you can convert muscle powered to electrical but again there is no such thing as free energy just as there is no way to destroy energy. You can only convert energy.
@@thesteadingoffranya4423 ok youvare righ
We Pakistani run car with water but the man who did this government disappear him
If i ve money i can do this in one month with my team but i cant purchase 15 kva dynmo generator and dc current motor and gears and frame card etc ok thnx to talk with you
You will never have free energy
