Another English/Metric "Spacecraft" Problem

SuperDry writes "There's been another spacecraft failure that's been attributed to an English/Metric units problem, this time at Tokyo Disneyland's Space Mountain. An axle broke on a "spacecraft" (a.k.a. roller coaster train) mid-ride, causing it to derail (nobody was hurt). The final investigation report has been released, and the root cause has been determined to be a part being the wrong size due to a conversion of the master plans in 1995 from English units to Metric units. In 2002, new axles were mistakenly ordered using the pre-1995 English specifications instead of the current Metric specifications. Apparently size does matter, even if it's only a 0.86mm difference."

They never call to mind that a locomotive is a modern invention, and, for want of access to works such as we have referred to, they are not informed that a railroad is an ancient institution (if we may apply such a term to such a subject). They never have dreamed nor ever imagined that this peculiar kind of road was invented and in use several centuries ago, but, like the great auxiliary, the locomotive, was very defective and simple in its primitive state, and since that time, like the latter, has been subject to vast and continued improvements. Before, however, we enter upon the subject for which these pages were designedN" the history of the first locomotives in America"Nit will not, we trust, be deemed inappropriate here to devote a small space in our work in describing the peculiar kind of road upon which the locomotive travels, now known universally as the railroad; and to such information as we have gathered of its origin and early progress. Various devices have been employed, from the period when wheelcarriages were first used, for facilitating the movement over the ground in transportation. These devices, however, were mostly limited to the smoothing, leveling, and hardening the surface of the way. The early Egyptians, in transporting the immense stones they used in the erection of the vast pyramids from the quarries, learned the advantage of hard, smooth, and solid track-ways, and the remains of such, formed of large blocks of stone, are said to have been found on the line of the great road they constructed for this purpose. The ancient Romans made also some approach to the invention of railroads, in the celebrated Appian Way. This was constructed of blocks of stone fitted closely together, the surface presenting a smooth and hard track for the wheels. In modern times such tracks or roadways were constructed in several European citiesNLondon, Pisa, Milan, and many others. The first instance on record of rails being used on highways was as early as the year 1630, over two and a quarter centuries ago. They were invented by a person named Beaumont, and built and used for the transportation of coal from the mines near New castle, in England. Old Roger North alludes to railways as being in use in the neighborhood of the river Tyne in the year 1676, and he thus describes them: The rails of timber were placed end to end and exactly straight, and in two lines parallel to each other. On these bulky carts were made to run on four rollers fitting these rails, whereby the carriage was made so easy that one horse would draw four or five caldrons of coal at a load. We read of railways existing in Scotland in 1745, at the time of the Scotch rebellion. These railways were laid down between the Tranent coal-mines and the harbor of Cockenzie, in East Lothian. Improvements were made on these roads and continued until 1765, 2 when they began to assume the forms of our present roads, even to the use of flanges upon the wheels; but up to this period no iron surface was ever heard of The mode of constructing a railroad at that period was as follows: After the surface was brought to as perfect a level as possibleNor incline, as the case might be Nsquare blocks of wood, called sleepers, about six feet long, were laid two or three feet apart across the track; upon these two long strips of wood, six or seven inches wide mod about five inches deep, were fastened by pins to the sleepers, and parallel to each other, but about four feet apart.

For one reference Roemer used a mixture of ice, water, and salt to reach the lowest temperatures then attainable in the laboratory, which he called zero. His other reference was the boiling point of water, which he arbitrarily designated as 60 degrees.

    Fahrenheit returned home to make thermometers like Roemer's. In 1714 he overcame technical difficulties with alcohol thermometers by substituting mercury as the expanding liquid. The use of mercury extended the range of temperature measurements from well below Roemer's zero to well above the boiling point of water. Furthermore, mercury expanded and contracted more uniformly than the other liquids then in use. As a result, Fahrenheit could mark his mercury thermometers more accurately and with finer divisions.

    By 1724 Fahrenheit had adopted a new scale, similar to Roemer's but with much finer divisions. For the zero point he chose the same reference as Roemer. However, since his thermometer was intended for meteorological observations, he wanted a second reference point that would be nearer the maximum observed temperature for weather. He chose the normal temperature of the human body as the upper reference point, which he called 96. Fahrenheit gave no reason for his choice of 96, but it may have been due to his desire for a finer scale and because 96 is evenly divisible by 2, 3, 4, 8, and 12.

    Why didn't Fahrenheit choose the freezing point of water for his zero reference, as Newton had done before him and as Celsius did later on? Perhaps Fahrenheit was influenced by Roemer, or he may have wanted to avoid the inconvenience of repeatedly using negative temperatures during winter. Also, in the early 1700s it was widely believed that water did not always freeze at the same temperature. Soon, using his newly calibrated thermometers, Fahrenheit learned that water always froze at 32 on his scale. He immediately added this third reference point to his instruments.

    Don't give me that crap about how much better the US economy performs than the EU. The median standard of living in the EU is higher than in the US. The US economy is great at producing wealth at the top, but conservative Americans have an aversion to using the economy to solve social problems ("communism! class war!"). I think this is a major reason why Europeans view the US as "backwards". Yes, both the US and the EU have economies that have solved the problems of food, shelter, and medicine. But the US has not seen to distributing those solutions to the people.

    Many Americans have an ingrained sense that the only job of the economy is to grow. Things like social nets and environmental protections interfere with the ability of the (total) economy to grow at the fastest rate possible, so they must be inherently bad. This is the unifying economic philosophy of the conservative Republicans: government itself is inherently bad precisely because it siphons money (taxes) away from investment and consumption. If you believe in Reaganomics ("a rising tide lifts all boats") this makes some sense. But in the real world, it leads to a morally bankrupt society obsessed with money.

    A friend of mine in college in the late 80's did an internship with Disney Imagineering. At the time, they were redrawing plans for several attractions that were to be copied almost exactly from California and Florida version for use in Euro Disney. There was great concern that the Imperial to metric round-off would be a problem. The contractor's union in France mandated that they only use metric units in the blueprints, which is reasonable. But if you're trying to duplicate a ride that was originally designed in Imperial units, you need to keep in mind quite a few significant digits when you're measuring. For example, a section of track in a given ride might be 10 feet in the US. In metric that's 3.048 m. Would the French contractors really measure to that precision? Or would they round off to 3.05 or event 3.0? They were concerned that roundoff might be systematic causing the errors to accumulate in one direction. This was a big concern, and there were debates over whether some rides needed to be redesigned in metric from the start and possibly give up economies of standardized parts.

    That this happened in Space Mountain is also interesting, because Space Mountain was the first rollercoaster to have ATIS (automated track inspection system). Since it was a tightly wound coaster in a confined space it was difficult to do visual inspections. ATIS uses two techniques to detect problems with the track. The rails are actually tubes and they're pressurized in sections. When small cracks start to develop, the pressure drop is detected. Sensors also time cars through different sections of the track. If there is a trend of cars slowing through a section over time, it indicates that the ties between the rails are starting to give. ATIS is so much better than visual inspections at detecting problems early that it's used on most modern roller coasters.

  50. Canada: the metric, imperial and american systems by procsyskernel · · Score: 3, Informative

    Hello, I live in Montreal, Canada. Here we use three different systems; officialy, we use the metric system, for example: - road signs and cars are in kilometers - the pumps calculate gas in liters - outside temperature is indicated in Celcius by the medias - only the metric system is shown in school But, we also use the imperial system, which is the system of the English empire that we used previously (Canada is part of the Commonwealth as being one of the oldest english colonies). For example, lots of my uncles and aunts (I'm 25) will talk to you about their cars doing miles per gallon, miles per hour, etc. They will also buy stuff at the store in pounds. I personnaly weight myself in pounds and mesure myself in feet. That is not close to change... even if then babies are weighted in kilos at the hospital, and measured in centimeters, they also indicate the conversion on the official papers, otherwise the parents don't have a clue. Also, I personnaly have trouble reading the inside temperature in Celsius... I know exactly how warn I like it, but it's in Farenheits... (even if we only calculate the outside temperature in Celsius, and nobody converts them to understand, not even my grandfather). Also, I have never seen someone calculate the temperature of the pool or spa in Celsius... Don't ask me if 25 Celsius is hot or cold for a pool, I really don't know ! And finally, we also use the American system. The american system is different that the imperial for some measures like "gallons". For example, an imperial gallon is almost exactly 4 liters, while an american gallon is 3.78 gallons... this is why it's always frustrating when you put windshield washer fluid in your car, and they sell you the fluid in 4 liters containers, but the damn US car's ww fluid container is only 3.78 liters ! You always have to carry the damn container because they is always some left... Also, all the contruction is done in feet and inches. We produce the materials, lots of them, but none of it is produced in meters, because the main market is the US, so they just don't bother with our small market and produce everything in feet. This means that architects and engineers, even if they only learn the metric in school, must learn the english and american systems when in university. The same applies for a lot of people that do plumbing, mecanics, and even furniture. However, the people here always use the same terms as before, even if the units have changed; for example, we will say "a pint of milk", even if nore it's no more a pint, but it's a liter... Which system I prefer ? Well, I don't really care... I find the metric system the best, but I would certaintly have problem purchasing furniture in centimeters when all my house as been constructed in feet. I do like the feet and inches, because I find them conveniently easy to estimates, but when you start evaluating distances that are longer than the terrain my house is built on, I will say "300 meters further, turn left"... and will calculate in kilometers. The thing is, if the damn US could convert to the same thing as the rest of the world (which will never happen, or perhaps never before China is the new superpower), we will be stuck with the three systems in Canada...

    We'll, it's close to the history such things -- the use of a foot as the standard of measurement dates back to prehistory. Sometime in the 13th century, King Edward I of England ordered a permanent yardstick of iron to be made for use as a standard by the whole kingdom and declared the foot to be 1/3 of that length and the inch to be 1/36. That yardstick is pretty close to today's measure of a yard. However, King Edward II reverted back to the more primative measure of an inch as "three barleycorns, round and dry."

    I pulled this from an article that I found via Google. From the same article:
    In spite of repeated requests in Congress, there was no legal length standard in the U.S. until 1832. More or less authentic copies of the British copies of the yard were used as length prototypes. In 1832, the Treasury Department decided to admit as a legal Yard the distance between the lines 27 and 63 of a certain bronze bar, 82 inches in length, bought in 1813 in England for the Federal Survey Department. When the British yard bar, which was destroyed in 1834, was replaced in 1855, a new bronze copy No. 11 was sent to the United States which became the legal American Yard Standard.
    Also from the timeline:
    "1959 - Australia, Canada, New Zealand, South Africa, the United Kingdom, and the United States adopted common standards for the inch-pound system in metric terms. One inch was made equivalent to 2.54 centimetres and 1 pound was made equivalent to 0.453 592 37 kilograms. (The Coast and Geodetic Survey, which had used a slightly different conversion factor previously, retained their established relationship of 1 inch equaling 2.540.005 centimetres because of the extensive revisions which would be necessary to their charts and measurement records. The resulting foot based on this retained conversion is known as the U.S. Survey foot)."
