Please help, I'm stuck on this problem:An aluminum wire and a steel wire, each of length 4m, are hung from the ceiling. A 7 kg mass is suspended from the lower end of each wire. The aluminum wire has a diameter of 1.1 mm. What must be the diameter of the steel wire if it is to stretch the same distance as the aluminum wire, so that the two wires maintain equal lengths after masses are attached? Young's modulus for aluminum is .70 x 10^11 Pa and for steel it is 2.0 x 10^11 Pa.
With the usual symbols E= FL/eA, so F = EeA/L Call the aluminium wire '1' and the steel wire '2'. The tensions are the same (weight of 7kg) so: E?e?A?/L? = E?e?A?/L? Since the extensions and lengths are the same e?=e? and L? = L? so these cancel: E?A? = E?A? A?/A? = E?/E? Let the diameter of the aluminum wire be d? mm. Since the cross-sectional areas are proportional to the diametera squared: d??/d?? = E?/E? d? = 1.1 x √(0.70/2.0) = 0.65mm
How much wire is required?
Length of wire is L = R*A/p SI units must be used, so convert radius to meters: r = 0.0254 / 64 m using 25.4mm = 1 inch r = 3.969*10^-4 m (0.3969mm) So cross-sectional area is A = pi*(3.969*10^-4)^2 m^2 A = 4.95*10^-7 m^2 The average resistivity of nichrome is p = 1.1*10^-6 ohm-meter So the required length of wire is L = 2.2 ohm * 4.95*10^-7 m^2 / 1.1*10^-6 ohm-meter L = 0.990 m
there is a loose wire in my labtop charger wire. can i fix it or prevent it from happening.
Loose wires just happen - from the way a cable is bent, moved, stored,wrapped, etc... I think (providing it doesn't happen right after you get the product) that it's pretty much normal wear and tear over time. You could try to repair it, but it would involve removing the cable sheath and re-attaching the loose wire which may need soldering. You're probably better off just buying a charger. In my experience, cables tend to last longer if you don't tightly wrap or twist them during storage; I generally just loosely fold them.
How do electric and other companies decide on strung wires in consideration of snowfall?
Utility companies use a set of standards to determine the maximum tension in pounds that will occur on a wire due to wind, ice, temperature, wire size, wire type, span length, and support structure strength (poles). The normal loading criteria is based on a 8 pounds per square foot wind loading, ?” of radial ice at 0 degrees F. The NESC limits the conductor tension to 60% of the maximum rated tension of the conductor used or 2000 pounds, whichever is lowest. Hope this helps, Newton1Law
I dont understand it I am trying to get a 1ohm load on a 2ohm dvc speaker but cant figure out how to tell if the wire you connect in the postive terminal on the sub in a neg wire or positive how do you tell what the gray line is on this diagram positive or negetive and how to tell. thanks
You are wiring the sub in parallel. from the positive terminal of the amp you connect both positive terminals of the sub, and Viceversa for the negative. The wire is either positive or negative depending on which terminal it touched. Make sure your amp can handle an impedance of 1 ohm.
I need a wiring diagram for a 1983 honda rebel, its a 250cc parallel twin, i really need the ignition wiring diagram but i can't seem to find one. If anyone knows the letters (xx250,xx125) then that would help to. Thank you in advance.

What's the best kind of wire to use that can stand being kilned?
that really depends what you want to do and how high you are going to fire. Generally nichrome 80/20 wire should be OK until cone 9. Then there is Kanthal which will withstand even higher temperatures but is more expensive than nichrome. You could get either probably in electronics supply houses. If you do lowfire, maybe up to cone 06 or lower steel will probably be OK. The surface of the steel will oxidise and so get clearly thinner, keep that in mind. Generally your wire and the clay should not be in direct contact because they have different thermal expansion coefficients. Depends how rigid your wire is if it will lead to major damage to your piece. But if you wrap your wire with paper before you put clay around it it is probably OK as long as you don't enclose the entire thing with clay into a hollow space. But it also depends on what exactly you are trying to do, e.g. what kind of clay you are using. Mostly people use wire with clay for making beads. If that's what you are doing you can also look up bead making techniques.
I have a Trane Heat pump AC/Heat. There are several wires and Im a little stumped? There is a Tan wire*which the book does not show) and a black wire that is labled X1 on the old one but is not in the new ones book? I have also been told NOT TO hook blue wire up to the B port?? But if not, not sure where to put it?
Go get an HVAC technician to install it. You'll have at lot less headaches
