TDSB Canadian Football program
Which high schools of Toronto District School Board has Canadian Football program? So far, I know that York Memorial, East York, Leaside, Etobicoke, Richview and Martingrove have their Canadian football program?
 * Well this is a list of the current standings and here is a list of all the secondary schools in the TDSB. Easy enough to match them up. CambridgeBayWeather (talk) 20:21, 19 February 2011 (UTC)

introduction to business
what does it mean to say that quantity is “design into”a product.
 * That exact wording is gibberish: you probably meant to type
 * ". . . quantity is "designed into" a product."
 * but have failed to amend the grammar when (as I suspect) you paraphrased your homework question.
 * However, I suggest you recheck the original question, which very likely actually reads
 * ". . . quality is designed into a product."
 * This is a common concept, whereas designing quantity into a product is not, although it could be a rather strange way of referring to something related but different. If "quality" is really the issue, come back and confirm that that's so and we can point you in the right direction. Also, please sign your posts by typing four tildes (a tilde is this ~) in a row at the end: the system will automatically convert that into a source, time and date; otherwise we don't know who's saying what when. 87.81.230.195 (talk) 12:14, 19 February 2011 (UTC)


 * I agree what was meant was "quality is designed into a product". 92.15.16.146 (talk) 13:00, 19 February 2011 (UTC)


 * That simply means it's designed to look like a (high) quality product, even if it isn't. See Quality (business).--Shantavira|feed me 13:38, 19 February 2011 (UTC)


 * Another interpretation of the quality statement is "quality is not an afterthought; we had quality in mind when we began designing our widgets, and quality influenced our decisions about materials, function, and so forth." I'm not disagreeing with Shantavira, whose suggestion focuses mainly on appearance ("make it look like a quality product"), only saying that other messages are possible. I'm also not saying the statement is necessarily true.  It could simply be a marketing claim, or an article of faith (and what is faith without good works?).
 * The only sense I can make out of quantity being designed in would be something like "we designed our product to hold (or produce) a large quantity of" whatever the product holds or produces. "When we planned the MegaTrolley shopping cart, we designed it to hold such a quantity of groceries that you'd need a second car to take them all home." --- OtherDave (talk) 14:13, 19 February 2011 (UTC)


 * Just a guess: Quantity is designed into a product may refer to the typical modular design of consumer goods.  If you need to repair a car / a PC / whatever, the procedure is to remove the faulty module X0 and replace it with a new module X1.  If you own a Stradivarius or a Jugendstil desk (where quantity is not designed into the product) your luthier / arty carpenter will charge more than the price of a cheap fiddle / an IKEA desk.  In simple terms, quantity is in the design of the common house brick, it is not in the design of the pendant vault of Henry VII's chapel at Westminster Abbey.  Not surprisingly, there are more house bricks than fan vaults.  --Cookatoo.ergo.ZooM (talk) 19:37, 19 February 2011 (UTC)
 * "Quantity is designed in . . . " could also imply that the product had been designed to maximise the ease of making it in large quantities (as in the case of cars produced on production lines by the likes of GM, as opposed to cars essentially hand-built as MG's originally were), but as I implied in my initial response, it seems likely that the OP misread the original question. "Quality is designed in . . .", as OtherDave's first para says, generally implies (truthfully or otherwise) that the design of a product incorporates considerations of quality from the outset, rather than these being added as an afterthought. 87.81.230.195 (talk) 00:02, 20 February 2011 (UTC)

Presure exerted on a brake disk under emergency braking situation
I have a university assignment due in yesterday, and I'm just finishing up now. My biggest source of worry is I get ~1.75 bar for the pressure on a brake disk when emergency braking, but when my friends worked it out together they got ~70 bar. The force we exerted was 300N on the pedal, which gave 100bar pressure. The master cylinder diameter is 16mm, the brake calliper cylinder is 39mm, the brake pad contact area is 3400mm^2. My calculations are: Using the knowledge that no pressure is lost in a closed system, and the diagram (right), I know that F1/A1=F2/A2. From that I can I know that F2=(F1/A1)A2. I know the force I put in, as measured in experiment 1, and I can calculate the necessary areas from the two diameters measured earlier and the formula A=πr². From this information, the knowledge that pressure is equal to force divided by area, and the total contact area between the brake pads and disc, I can calculate the pressure. F1=100N, A1=π*8², A2=π*19.5² – therefore we can find the force F2 to find the pressure. F2=(100/(π*0.008²))*(π*0.0195²)=594.140625. Pressure=F2/3.4*10-3=174742N/m². Pressure = 174742/105=1.75bar. Does that seem reasonable? Thanks! 192.150.181.62 (talk) 13:48, 19 February 2011 (UTC)

zippo lighters
i have a zippo windproof lighter that is black with a white playboy bunny on it dated june 2005. my question is about the bottom of the lighter being gold in color. is this a collectors item or a special edition? i have never seen one made like this.76.242.185.96 (talk) 19:18, 19 February 2011 (UTC)

Is it brass? There are brass Zippos about and it's possible they used brass as a foundation for the enamalled finish.Hotclaws (talk) 20:52, 19 February 2011 (UTC)


 * I expect that there will be collectors for this sort of thing, but I suppose you want to know how much it is worth. Graeme Bartlett (talk) 01:21, 20 February 2011 (UTC)

Jewish online shop closed on Saturday
I tried today to buy online from a well-known Jewish provider of photographic material and surprise: it closes on Saturdays. The funny thing is that you cannot order, but you can browse the catalogue. Even if I understand that Jews don't work on Saturdays, they wouldn't be working, if they left the server taking orders or if they let non-Jewish do the work, would they? Where in the Torah does it say that something about online shops? Quest09 (talk) 19:52, 19 February 2011 (UTC)


 * First, when thinking about Shabbat laws, it's not a Biblical issue but a Rabbinical one. Big difference: it means you don't go looking around the Torah for them — you look at the agreement of Rabbis who have looked around the Torah for them. You look at the evolution of decisions over the years, you don't refer back to the original too often. (Judaism is not a "do it yourself" religion like a number of sects of Protestantism are.)
 * Commerce is generally prohibited on Shabbat, as I understand it. As for whether e-commerce is prohibited, I think it is still an open issue. There is a very thoughtful discussion of this here by a Rabbi, which notes that depending on what model of commerce you assume e-commerce resembles (e.g. is it like a physical store, or is it like a vending machine?), you get different answers. --Mr.98 (talk) 22:15, 19 February 2011 (UTC)


 * That would be strictly a decision of the owners, who have apparently decided that they can afford not to allow Saturday shopping. I've known Jewish merchants who kept their stores open on Saturdays because most of their customers were Christian and Saturday is typically shopping day for Christians. The Jewish proprietors, though, might take Saturdays off and leave Gentiles in charge of running the store that day. ←Baseball Bugs What's up, Doc? carrots→ 07:48, 21 February 2011 (UTC)


 * Wikipedia of course has an article about the Shabbos goy, who takes charge while the proprietor can't. PhGustaf (talk) 08:00, 21 February 2011 (UTC)
 * One of the rules in Judaism is you're not supposed to encourage or allow other Jews to violate Jewish laws. So allowing e-commerce on Shabbat would allow other Jews to violate Shabbat. Now I guess the question is, what hours do you shut the site down for? If you have customers in Australia, Europe and all the way across the U.S. to Hawaii, that could be a problem. -- Mwalcoff (talk) 04:15, 24 February 2011 (UTC)
