- Q: I learned a couple of books could help me pretty well, but i don't think i need to buy those books just to make the mirrorIt would be very nice if someone could just tell me the major steps in the fabrication of a parabolic mirror, just to get me startedLike how to make the basic parabolic shape, what material to use for the reflexion(aluminum?), how to polish it, tips, etc, and i think i could fend with the rest.Thank you very much!
- First make it spheroidal, then figure it into a paraboloidSome books [e.gTexereau's (in French) and Allyn Thompson's] are onlineThe links are at telescope makers' Yahoo! webgroupsYou make the mirror out of a plate glass disk or Pyrex glass diskA first project is usually in the 4 to 10 rangeYou first grind out the concavity with coarse grit and another glass diskA spheroidal shape occurs naturally as one disk becoming concave and the other convexThen you smooth the concave surface with progressively finer abrasive gritThen you polish the surface with cerium oxide or jewelers' rougeThen you optically test the surfaceThen you use appropriate polishing strokes-selectively removing glass to change the the shape into a paraboloidThen you clean it and have it aluminised in a vacuum chamberFor someone with experience who is all set up a 4 mirror can be ground, smoothed, polished, figured, and aluminised in a dayAs a first project it would take a few weekendsThere are 20+ telescope making groups/classes/workshopsSome are listed at the Stellafane websiteThe suppliers of glass and grit in the US are GotGrit, Willmann-Bell, and Newport Glass WorksA 4 mirror starter kit (with two disks, the abrasive, the polish, and the pitch) is about $80NGW and GG show some prices at their websitesWB will email the telescope-making supplies section of its catalogThere are telescope-making Yahoo! webgroups, like atm_free and make_your_own_telescopeThey list weblinks to a few online booksAnd a telescope making webringAnd a good forum-the ATM Mailing List.
- Q: I have a Coleman stove (2 burners, no grill) and a fire pitSomething good please and not too bad for you:)
- Another thing that will give you an idea is to call the utility companies and ask them the average billThat is the best/worst indicator of good/bad insulation.
- Q: If the price of aluminum (a substitute for steal) rises, what happens to the steel producer's supply curve? The supply curvea) shifts to the leftb) shifts to the rightc) remains unchangedI am an undergrad in economics and this question should be extremely easy for meBut I am convinced its C, because a higher price for the substitute would create more consumer demand for the product that is cheaper or is less expensiveSo, the demand curve for steal would shift right and the new equilibrium would be at a higher quantity sold and at a higher price without a change in supplyBut the book says the answer is BBut I totally disagreeWhat am I missing?Help me out.
- Aluminium is a very poor substitute for steel, but that's largely beside the point The answer is CAny other answer requires you to consider second round effects and (preferably) for the production of steel to be a perfectly competitive market (clearly, it isn't)Suggest the book's authors probably got their words mixed up when writing the question.
- Q: A rain gutter is made from sheets of aluminum that are 2323 inches wideAs shown in the? figure, the edges are turned up to form right anglesDetermine the depth of the gutter that will allow a? cross-sectional area of 5151 square inchesShow that there are two different solutions to the problemRound to the nearest tenth of an inch.
- Assume you mean 23 and 51 as numbers sometimes are repeated in this forum(23 - 2h)h 51 2h^2 - 23h + 51 0 h (23 +/- sqrt(23^2 - 4(2)(51))/2(2) h (23 +/- sqrt(529 - 408)) /4 h (23 +/- 11) /4 h 8.5 ; 3
- Q: I found in my sons room aluminum foil, and it had black burned residue on itbent spoons, with burned marks on it, q-tips and dixie cups with waterwhat could this be, what is he smoking or experimenting with? i already know he's doing drugs, but be specificwhat kind of drugs do you think he is using?
- he's doing heroin it can be weed, You should fine some help,do some research to check what the best for him and your familyDrug is not the easy thing to quit if he think he don't have a problems ,Good luck with all the decision you have to make .
- Q: Aluminium metal can reduce the hydrogen ions in a solution of hydrochloric acid to hydrogen gas, according to the equation:2Al(s) + 6H+(aq) -gt; 2Al3+(aq) + 3H2(g)a) Write half equations for the oxidation and reduction processes involved in this reaction.b) Use these half equations to explain why six hydrogen ions are reduced for every two aluminium atoms oxidised.I can do part a alright but I don't know how to answer part b and it seems so simple but I just don't get it! Any help will be appreciated and thanks in advance :)!
- A) Aluminium is oxidized: Al - Al3+ + 3e- Hydrogen is reduced: 2H+ + 2e- - H2 Now, you have to balance to number of electrons, aluminium gives three, hydrogen takes two, so the least common factor is sixHence: 2Al - 2Al3+ + 6e- 6H+ + 6e- - 3H2 From the above two equations, you have see that for every two aluminium atoms, six hydrogen ions are reducedI really hope I helped

- London - a giant capital town! I cannot believe of any keep that specialises in yarn promoting any rather cost effectively in my facetI could have got to move to Hobbycraft (now not that low-cost) or perhaps all of the means out to Uxbridge Market (good enough for me as I'm at the Metropolitan Line besides)Some nearby markets have haberdashery and wool stalls however as I have no idea wherein you're I cannot notably remarkIf you do not brain mail-order, then have a seem on the Abakhan website, which has all types.
