Here is a link to an explanation:

https://www.quora.com/Why-is-air-resistance-roughly-proportional-to-the-cube-of-speed

I understand that link is for air, but the concept Is true for any “fluid”. For all purposes of farm equipment, the soil is a fluid because it flows around the implement.

Actually, a lot of solids can be modeled as fluids when in small pieces. Fluidizing flour, sugar, and sand is how it handled on an industrial scale.

pretty much yea lol

>it's about possiblity and doing something because we can

so a neat thing to look at that serves no purpose...

it's not so much of needing a purpose, it's about possiblity and doing something because we can

what purpose would you want to build such a machine for?

didn't think of it like that but that makes sense

The entire problem is there's a set amount of energy you can get out of something. So the only way to make something "run for a long time" as a power source is to really really slowy take energy away from it. Why would we bother to do that?

There's simply no point.

Basically your question is like asking "if bank accounts run out eventually why haven't we just made a bank account we take money out of slowly?"

Because we want the money.

Because using it to power things adds drag to it and makes it eventually stop.

so we have no need for it other than a cool thing?

We have. All sorts of things can keep going for a long time. But... Why?

What's the point of a wheel that spins for a long time inside of a vacuum chamber suspended by magnets? It doesn't do anything, besides look neat. We already have devices like that, though. A digital watch can run for years on one little battery. The oxford electric bell is still ringing to this day.

Like this?

Probably because there's no point in making such a machine besides a neat curiosity that would require very expensive low friction bearings. The second you acknowledge it's not a perpetual motion machine, it's no longer interesting.

that does but what I meant was something of a power source

We...have?

I'm not sure I understand your questions. We humans have developed lots and lots of things that just keep going as long as you input some energy.

For example, there is a clock in New Zealand called the Beverly Clock, its been running since the 1860s without having to be serviced. That probably qualifies as a long time right?

I've been to factories that have had the some machines running non-stop for 40+ years, too.

I feel like we still haven't arrived at an "explain like I'm five" version yet, though?

So maybe something along the lines of... so there's a lot of important things that are different between wood and metals. As u/Lirdon said, metals are just raw elements (i.e. silver, nickel, etc.). The atoms in metals form a special type of bond with each other that's different from the bonds that we see in organic stuff like wood. The type of bonds formed by metals lends itself really well to going evenly from a solid into a melty liquid when you heat it.

Wood is a mix of many types of organic, non-metal compounds. The bonds that these atoms in these compounds form tend to be much, much stronger.

When non-metal stuff with those stronger types of bonds gets heated, sometimes it goes nicely from being a solid to a liquid (like the plastics and waxes that u/tdscanuck mentioned). But sometimessss things get real spicy instead. In the case of wood, the compounds completely break apart into ash, tar, and the CO2 gas. Metals don't really have the option to "break apart" into other things since the nickel, copper, etc. atoms are already in their most basic form.

Maybe? Hopefully the people who actually know chemistry can come fix this lol

Edit: apparently metals can also burn but there's a bunch of reasons when metals common forms we see them don't very often. https://www.wtamu.edu/~cbaird/sq/2018/02/18/why-dont-metals-burn/

Oh, you ready to blow?

Well I'm a mushroom cloud layin' motherfucker, motherfucker.

There is always more than we can imagine.

Can you source this? I doubt it's true

EXACTLY! But it sure is fun to drive!

Yup. This is one of the big dangers of tractors. They have enough torque and the tires are built to get traction on dirt that they can be very easy to flip over backwards and crush the driver.

Id like to know what equipment you’re looking at, a John Deere S 980 has like a 900hp MTU engine. The new Nexat has an 1100 hp engine. Some silage choppers have 11-1200 hp engines. A typical 4wd modern tractor is 380-600 hp with 900-2000 lb-ft of torque.

If you take the LeTourneau L-1850 and do a per unit calculation, it accelerates quicker than a late ninety’s Top Fuel Dragster.
