I'll see your 62' and raise you 120'.
I couldn't find another pic of the big blade. Could it be for furrowing? Or maybe just ripping? Or gophers?

How could they use a 120' bar if the Earth wasn't flat. :haha:

When you lift it in the middle, it deflects to match the curvature of the globe.

The tractor was designed to speed up farm equipment on the road while being stable, the speed record is just for shits & giggles.
And the Honda does actually mow just not at the same time...

Why? I'd say for the military given the time frame and color.
Yeah but why a 30 cylinder, 2.5 ton monster to get only 400 horsepower?
Because horsepower don't mean shit, torque is what does work.

Any kid from elementary school science can see through that lie. Same torque can be obtained from the motor in an electric clock. Just change gear ratios.

It is a 19.5 horsepower per liter engine. If diesel, then acceptable for that period. If gasoline, it was a marginal design. Which would explain why it was only made for a short time. Too little speed to provide necessary torque - due to insufficient horsepower.

Rhianne 07-17-2019 08:07 AM

TW is right. HP is a calculation taken directly from the torque (HP = Torque lb-ft x RPM / 5252). The low HP figure is a result only of the low-revving nature of the engine.

Quote:

The Chrysler A57 Multibank is a 30-cylinder 1,253 cu in (20.5 L) engine that was created in 1941 as America entered World War II. It was born out of the necessity for a rear-mounted tank engine to be developed and produced in the shortest time possible for use in the M3A4 Lee medium tank and its successor M4A4 Sherman medium tank. Each had lengthened hulls to accommodate the A57.

That electric clock motor won't provide enough torque to overcome the frictional loss in all the gears it would take to do anything useful.
All the gears in the world won't change the torque the motor produces, just multiply the torque by reducing the speed of the output thereby reducing the calculated horsepower.

Theory is bullshit, torque does the work.

Who say cheaters never win, both NHRA and NASCAR checked the Carb, Intake, Bore, Stroke and Heads,
but not the bottom end. Taking off the Intake they should have spotted the cam bearings though.

BigV 07-18-2019 09:55 AM

I'm curious about how those connecting rod internal bearing races work. They look like in the picture that there's a race on the bearings... Which makes me wonder how they got the bearing/race onto the crank.

Any help?

xoxoxoBruce 07-18-2019 10:10 AM

This crankshaft is a one piece and is heat treated and surface hardened. The connecting rods and bearing races are split in the middle. The bearing retainers are also split in half and assembled around the crankshaft, and split races are in the block and main bearing caps. The roller bearings run directly on the hardened crankshaft.

BigV 07-18-2019 10:38 AM

Thanks, key phrase "split races", is a new thing to me. I think I can imagine it now.

Thanks!

Diaphone Jim 07-18-2019 11:57 AM

Were the rollers illegal?

xoxoxoBruce 07-18-2019 09:59 PM

Oh yes, very. Especially NASCAR who wants to make everything same same. Using those bearings cut down on frictional losses and you could use a smaller oil pump that took much less parasitic power from the engine. Might be good for 5 mph compared to a legal engine, and in NASCAR that's huge. NHRA it would be OK in modified classes but very illegal in stock, SS, even FX classes.

You have assumed conventional gears.

And have totally ignored the point. Same torque can be provided by all sorts of horsepower - high and low. Irrelevant is torque when speed also matters. Only increased horsepower means sufficient speed at that torque. Only horsepower matters. Even a 2 liter four cylinder engine can provide the same torque. But does not have speed.

Obviously that torque myth is popular among many who forget that simple formula taught in school science.

Torque is obviously irrelevant if enough horsepower does not exist to provide minimal speed. Only horsepower matters.

Why do eighteen wheelers with 350 horsepower engines have enough torque for 60,000 pounds? Many gears. Which eighteen wheelers get up to speed faster? Those with 500 horsepower engines. Both have same torque. More horsepower means better speed (and acceleration).

Horsepower is the relevant number.

How did Shell create a 100 MPG car in the 1950s? A two horsepower engine had plenty of torque - and not much speed. Simple multiplication.

xoxoxoBruce 07-19-2019 08:35 PM

Yes, I assumed conventional gears, my bad for not considering your magical frictionless fairy gears. My only excuse is I'm stuck in the real world.

You have it backwards as usual, horsepower is the product of torque times speed over constant. The 30 cylinder engine was designed to produce the torque they needed at the speed they wanted. Yes the hp rating could be increased by increasing the RPMs, but that would be stupid. All that would be accomplished is more wear on the engine and the need to gear it back down to a usable speed. They already had the torque they needed and Torque Does the Work.

Your 2 liter 4 won't get far in a tank or a semi.

The basic bicycle is a pretty simple design, but it took a long time and lots of dead ends to get there. I have a feeling clothing had a lot to do with it.

It was designed with sufficient horsepower so that gears could select a torque necessary to maintain a speed. Horsepower (not torque) is always the relevant parameter.

As usual, due to too much emotion and insufficient knowledge, you again got it wrong.

4 cylinder engine can produce that same torque. But insufficient speed - due to insufficient horsepower. You also got that wrong.

Anyone not educated by hearsay (who can do simple multiplication) would know that. Only motors with sufficient horsepower can produce a torque at required speeds. Somehow that multiplication is just too hard - the routine expression from another lesser educated man called George Jr.

Meanwhile, that engine apparently had a very short life span due to its low performance numbers.

Innovations were necessary because the human output too much torque. That large front wheel converted high torque - low speed into low torque high speed. With gears and chains, then smaller wheels could accomplish the same conversion. And provide the many different torque - speed ratios that a bike needs for changing terrains.

But again, it all about that simple concept taught in school science - the product of torque and speed. So that a much less than 1 horsepower engine (the human) could adapt to changing loads.

BigV 07-21-2019 08:54 PM

hey tw

you're wrong about your unswerving devotion to the temple of horsepower.

Let me ask you this. When you have a nut on a bolt to remove (or tighten), do you, with your static, unchanging amount of personal horsepower, use your fingers and thumb, or do you use a wrench?

Ass backward as usual, the engine is designed for torque, they sure as hell don't add a bunch of extra pistons to make more rpm. Gear selection dictates the speed the work gets done, torque does the work.

It's the site of Redstone quarries in North Conway NH. They quarried and polished granite like the massive column in the pic. I don't think they lasted long working from the late 1800's and shutting down sometime in the 1910's.

I didn't know the site was there until I rode into it.

Clodfobble 07-28-2019 04:00 PM

Granite's expensive, right? Is it not worth someone's effort to get in there and take that column? Or are there just too many trees in the way, do you think?

Griff 07-28-2019 04:17 PM

It's a state historic site now. I was surprised that amount of steel was still there. The column is accessible but there is a rail bed between it and the roads.

sexobon 07-28-2019 05:10 PM

You didn't ride your bike on top along the length of the column? After a balancing act like that, it could've been called Griffhenge.

xoxoxoBruce 07-28-2019 11:17 PM

It's amazing that machinery wasn't scrapped for the war effort.
Once you steal that column what on earth would you do with it?

Clodfobble 07-28-2019 11:19 PM

Carve it up into kitchen countertops?

xoxoxoBruce 07-28-2019 11:25 PM

It would have to be sliced and each slice polished, I doubt it would be cheaper that using slabs from the quarry in the end. But it seems a shame to cut up a polished cylinder like that, maybe erect it and put a statue of UT on top.

They dropped a CAT through the ice in the Arctic and had to retrieve it. I traced this picture back as far as Reddit but can't find any details.
Seems to me if the ice wouldn't hold the CAT, it wouldn't hold anything lifting it out of the water.
I thought maybe a barge mounted crane but the oil slick seems to be under ice. Damifino.

BigV 07-29-2019 09:51 AM

Griff, your short story was very exciting! When I saw the drive face of the lathe I gasped. I was thinking about turning (already cylindrical) trees (wtf??). But no. Great surprise ending!

Banana, lol.

xoxoxoBruce 08-10-2019 09:44 PM

This was the next step. A lot of work, a lot of money, they only built one. Crazy difficult to end up with a unit stiff enough to not flex or vibrate, hard enough to stand up to the roller bearings but soft enough to not crack, and perfectly balanced for high RPM.

Diaphone Jim 08-11-2019 12:05 PM
