Q:I have a project about the electrodynamic loudspeaker, but there is a material I‘m not knowing what it‘s used for.It is the spider, I know it‘s made from cotton. and I know where it is place, but i don‘t know what‘s its role in the electrodynamic loudspeaker. Also I am just an 11th grader so go easy on me with the explanation. Thx

The spider is just a suspension system to keep the coil in the centre of the gap in the magnet. You need the coil to be free to move in and out of the magnet gap, but not side to side. If you ever hear a speaker with a damaged spider, where the coil is rubbing and grating against the side of the magnet, you'll know how important it is!

Q:I need a bike to go around town. I have no clue about bikes so, can you help me?1) I live in Caracas Venezuela, which means a lot of uphill and downhill biking. Some have told me Buy a mountain bike but there are like eight gazillion different mountain bikes. Suspension, no suspension, 10 speed, 21 speed2) There aren‘t really bikeways here so i need good, safe brake systems. I know some bikes have brakes in the front and others have it in the pedals.what‘s better? What‘s cheaper on the long run?3) I‘m not using it for leisure only, so how can i manage to get some modest amount of cargo space? (say, a laptop)4) What‘s the difference between 20 and 26 inches rin? are they just for different sizes of person or is it something else? I‘m 1,80m tall (5.9 feet)5) Any other pointers you deem importantAll opinions will be thanked!

1) I live in Caracas Venezuela, which means a lot of uphill and downhill biking. Some have told me Buy a mountain bike but there are like eight gazillion different mountain bikes. Suspension, no suspension, 10 speed, 21 speed get a mtb, yes - but put street tires on it or get a hybrid - those have low gears no suspension - robs power go to a bike store, not a cheap dept store 2) There aren't really bikeways here so i need good, safe brake systems. I know some bikes have brakes in the front and others have it in the pedals.what's better? What's cheaper on the long run? any good bike will have front and back brakes controlled by cables and levers on the handle bars --coaster brakes are for kid bikes, and are not safe 3) I'm not using it for leisure only, so how can i manage to get some modest amount of cargo space? (say, a laptop) backpack is easiest 4) What's the difference between 20 and 26 inches rin? are they just for different sizes of person or is it something else? I'm 1,80m tall (5.9 feet) any mtb [mid price] that fits you [go to a bike store] will have 26 tires 20 is kid bike 5) Any other pointers you deem important get one that fits wle.

Q:I was thinking a magnetic-levitation suspension system but I don‘t have the technical know-how to build that. I didn‘t even graduate college so I‘m not really up to speed on my scientific skills. However, I suspect that the Hawking radiation from a mini-black hole would be sufficient to levitate it without a magnetic field, much like a water droplet hovers on a hot skillet due the Leidenfrost effect. But I really need to know for certain because it would be bad if the black hole got out of control. I briefly considered immersing the black hole in a super-cooled gas of weakly interacting bosons known as a Bose-Einstein condensate but decided against it for safety reasons.

A mini Klein bottle would do it. Take two Mobius strips of unobtainium and join side by side until a 3D structure is formed. Coat with magnetic monopoles. Wrap in superconducting metallic hydrogen. Power with a fusion reactor. That should be perfect.

Q:Under normal driving conditions how many miles should I expect to get from the stock run flat tires?

From all the corvette owners Ive talked to they said between 35 to 40 thousand miles.The corvette suspension system keeps the tires from wearing faster under normal driving conditions.They also like the fact you can get to a repair shop when they go flat.Very few Ive talked to have ever had a flat on there run flat tires.Best of luck.

Q:The question is what year mercesdes benz installed air bags in their vehicles?

I think the first year mercedes had a drivers side airbag was in 1986 or 87. The first mercedes to have dual airbags was a 1990 or 91.

Q:What kind of car suspension system, the advantages and disadvantages of the order of comparison

The following structural forms, McPherson, double A-arm (double-bar), trailing arm, torsion beam and multi-link. McPherson suspension for the front wheel, is a separate suspension, and is a very simple structure, compact layout, save space, front wheel positioning changes, with good driving stability. Therefore, most of the car before the suspension are used in this structure, the difference is mainly in the selection and shock absorbers, spring adjustment above. But the McPherson suspension in the use of shortcomings, that is, driving in the uneven road, the wheel is easy to automatically turn, so the driver must be forced to maintain the direction of the steering wheel, when subjected to severe impact, the shock absorber is easy to bend, thus affecting Steering performance, so many do not begrudge space and cost of luxury cars above and did not use this form. Double A arm hanging with two rocker from top to bottom, from the horizontal force by the two rocker at the same time absorption, pillars only carry body weight. So the lateral stiffness is large. As a result of the use of unequal long rocker (long short), so that the wheel in the up and down movement can automatically change the camber and reduce the track changes to reduce tire wear. And can also adapt to the road, tire ground area, good affixed. But because of the more on a rocker arm, so need to stand with a larger space, Honda's car before the suspension like to use this structure, Civic called the manipulation of the former, the front of the double arm A have some credit, sorry Is the 8th generation civic did not follow this structure, and the use of a lot of fans of McPherson regret.

Q:When an Account is Suspended from Yahoo Answers, How long does the Suspension last?

Suspensions are permanent. Yahoo has no idea what the word suspension means.

Q:im going to buy a 1965 impala,it has a 10 switch hydro system, should i take it out and put in airbags or leave it?

It depends on whether you want a hopper or not.The hydro system is complicated and heavy, however it has a ton of thrust, just what you want in a hopper. Now if you want handling as well as in the weeds attitude then by all means go with the air ride suspension, but be forewarned it's going to get pricey fast, so be ready to hand over a ton of green for the conversion.

Q:I am looking to convert a 03 Ford Expedition from Airbag to Coils. I am an experienced mechanic and have worked on many suspension systems but I have yet to work on a airbag. Now the airbag system on this truck is broken and is obviously depressurized. So to convert will a whole coil assembly just bolt right in? or will it need special modification? All info is welcomed, thank you.

Yea those aren#x27;t first car choices. Don#x27;t try to impress your friends with a car like those. You always tear up your first car any way. So a vette or power stroke is nothing for a first time driver. Look more 4 cylinder.

Q:So my 2001 Ford Expedition had an air suspension system that would turn on and off as needed. It messed up and would no longer turn on so we replaced it with a strut (springs) suspension, mainly due to it being cheaper. I have two questions on the matter:1. Is there much difference between the two in terms of performance/duration?and2. The steering wheel is now more delicate. It requires less turn on the wheel to turn the SUV. Is this due to the suspension being changed?

1. Not enough to sweat it. 2. Maybe. Without having a schematic on hand, it is possible the rig is equipped with speed sensitive steering and the airbags were part of that setup.
