The car thought to itself. I mean, it has seven other ones, why does it need to carry an eight around. So the car decided to do something it had been thinking about for awhile, and let the eight rod free, to play with its friend, Mr. Oil Pan.

I'm well aware of that. The old-style of rotary engines had a stationary crank and the chambers spun around with the prop. This configuration has a very high angular momentum that causes the plane to drift and makes cornering speed lopsided.

It's a bit hard to tell, but that triwing one appears to have a cowling and internal engine, which suggests that it's a multiple-bank radial, rather than a rotary. The spitfire is most certainly not a rotary-engined aircraft.

From the Wikipedia article on the Sopwith Camel -
"With rotary engines, the crankshaft remained fixed while the cylinders and attached propeller rotated around it. The result of this torque was a significant "pull" to the right. In the hands of an experienced pilot, this characteristic could be exploited to give exceptional manoeuvrability in a dogfight. A 3/4 turn to the right could be done in the same time as a 1/4 turn to the left."

It also killed a lot of inexperienced pilots - pretty crazy stuff really

It looks like a Fokker Dr.I to me, which would have originally had a rotary

Pretty easy to remember - rotary engines rotate the casing around. Radial engines have the cylinders radiate out of the center, but the cylinders themselves don't rotate.

More of "Horrible structural/engineering failures" but I couldn't find anywhere else on the forum for stuff like this: Why its a good idea to not build a shopping plaza on top of a capped landfill.







The story behind this is the literal last scrap of developable land in the Cleveland suburb of Garfield Heights was a capped landfill just southeast of the I-480 and I-77 interchange. Some developers decided it would be a great place for a new shopping center and got a bunch of major anchor tenants (Wal-Mart, Dick's Sporting Goods, Circuit City and a regional grocery chain) to sign on and built an $81 million complex in 2006-2007.

Five years later, and almost all of the anchors have vacated along with a bunch of the smaller stores after structural problems popped up from the shifting trash heap the place is built on and explosive levels of methane were found in the parking lot storm sewer system. The place is slowly turning into a ghost town; the major anchor buildings are being filled with discount furniture and dollar stores, many storefronts are vacant and a number of new construction projects have been sitting half-finished for two to three years.

Ha, I shop at the Giant Eagle there all the time. I've heard tales of "trash juice" bubbling up through the Wal-Mart plumbing. That Giant Eagle is billion times better than the one in Bedford so I hope it sticks around. Those cracks are around the back and side of the Wal-Mart there. I've seen 5-6 foot deep holes back there too.

That may be the only empty Wal-Mart in this country, and it's a fantastic sight.

Yeah, I was afraid of stuff like that when they built Fairlane Green shopping center, since it's on a industrial waste/toxic waste dump (I think Ford dumped paint and other chemicals there. Don't know exactly WHAT chemicals, but the article lists "industrial waste"). For years they were talking about building homes there but that didn't fly at all. I am surprised at how well it's done there and even more surprised that they have ponds on that land (some with stocked wildlife that's doing pretty well).

Don't have many mechanical failures to contribute to this thread, but I have an electrical one that may become a problem soon: I can hear my computer processing. More processing = louder noise. Louder than my fans and hard drives when playing games, and it's getting worse as time goes by.

nitrogen posted:

They always sound like that because it has an off/on ignition system. So the speed of the engine is regulated by the ignition system's duty cycle. In the Camel I believe there are two ignition systems. One for WOT and one for less than WOT. Engine management is accomplished by switching back and forth between the two while in flight

rscott
Dec 10, 2009


Yeah, most rotaries didn't have anything approaching a carb or any type of throttle control so the only way to vary engine speed was to cut the ignition. I think some of the later ones had manual air/fuel control so they would lean them out to drop engine power and then dump fuel for more power.

Same deal with this place, the landfill operated from the early 60s until the early 90s. There was an article in the paper around the same time they broke ground on the project about how the community in the valley just adjacent to the landfill has recently had a major uptick in people coming down with rare cancers and how everyone has stopped using their wells after their water started smelling like rotting garbage. The reporter hypothesized that given Cleveland's industrial roots there's likely all kinds of toxic and heavy industrial waste buried there.

They closed the one at Midway in Elyria, OH with no replacement. They were going to build a super center across the street, but backed out when they realized Midway was 9/10ths of the way to wasteland. I seriously dislike going there for anything. You need a truck to even drive on the roads.

e: It was built on a landfill, too. This one was just where the town threw its trash from its founding.

But, you see, this was mainly for a Walmart, and it's cheaper to do it the way they did. What, you think they'd spend money doing things properly?

Also, something something about groups of people and it being impossible to shift blame on a group.

They did dig out a bunch of the top layer of the landfill, there's a huge mound of buried trash just across from the shopping center: http://maps.google.com/maps?q=city+...p=12,98.43,,0,0 (its behind the gas station.)

I assumed they properly supported the buildings but just laid the parking lot down without really doing anything beneath it, hence the parking lot sinking around the building.
