- Q: What I really just want to know is the equation and basic concept on how to determine the optimal length of power cable needed to connect two poles while knowing only the linear density of the cable.It does not matter how much sag is produced because of limitations due to the strength of the power cable.
- The web page provides very thorough information and rigorous mathematical treatment relevant to the answer you seek. But it is just too much all at once to digest. So take it piecemeal, one bit at a time! First, you must realize that the sag of the cable is the single most important design parameter and strict attention to cable weight determines the optimal length. The equation of the catenary is the precise model but a parabolic approximation may work. (parabolic approx.) ymax = (3wl?) / ?√(64EA) P = wl?/(8ymax) Where ymax is the maximum sag l is the unstretched length w is the weight/unit length E Youngs modulus A Wire area P axial tension the curve is a parabola, which is a good approximation if the depth of sag is no greater than 1/8th of the span. Use the second equation to derive the induced tension P. H:=WL?/8S S:=WL?/8H L: distance between support S: Sag at mid-span H: tension (horizontal component of tension) The tension depends purely on the loaded geometry and the weight per unit length.
- Q: I recently replaced my 300W Bestec power supply with a 600W corsair power supply. the 600W electric cable (the one that goes to the wall outlet) is too short, can i use the power cable of the 300W power supply ?
- As long as it is the same gauge wire and willfit the adapter it will be fine.
- Q: There are a few thin cables running from the power button on your computer onto the motherboard. What are these cables called?
- It's not important to call them with a specific name. These are also cable. If your power button's cable is broken or damaged anyhow, you can change it by restart button. Just unplug the restart button's cable plug them in Power switch. Now your restart button is your power Switch
- Q: ive recently opned my external harddrive case so that i could put dat harddrive in my pc ... i was able to take out the ide cable but i cnt take out the power cable... plz help me.. how can i take out the power cable?
- Thats nothing new..Molex connectors often stick do not try to pull it out by the wires! grab it by the sides of the connector and wiggle it back and forth (side to side) it will come out eventually!
- Q: I have a 240 watt jbl subwoofer in my truck and a 200 watt kenwood amp i bought a kit of 550 watts.But i just bought a 900 watt visonik subwoofer and a 700 watt visonik amp. i need to know if i can use the 550 watt power,ground,rca cables for my new system?
- You can use them, but you won't get the most from your equipment. However, I don't think anyone will be able to tell the difference, it will be minuscule.
- Q: Why did my power supply entrance burn with the power cord cable the stats of my computer are: HP Compaq dx2250 Microtower PCProgram: Windows 8 32bitPowerSupply: 500w MaxGraphics Card: Nvidia Geforce GTX 550 tiWhy cause it to burn? What should I do? Change the power supply or buy a better power cord cable. The cable that burn, I bought it on OKorder for $2, I am not sure if this cause the problem, but for sure I need to buy a power supply because the entrance burn. What should I do? Is my computer stable with all this stats? What cause this to happen? Was the cheap power cord fault? I don't know, please answerThank You,
- A dodgy power cable can very easily singe or burn the power socket on the computer. In general, the lighter the cable, the more dodgy it is. $2 is nothing - I would buy a more expensive cable. The cents you save isn't worth it when your house is on fire. It's impossible to know whether your power supply or other computer components suffered any damage because of the electrical fire. You could try testing with a multimeter, but you should probably replace the power supply at a minimum.
- Q: i have a cable modem that i lost the power cord to. i found another that fits but the output listed on the adapter is 12.5vdc. the modem lists +12vdc. can I use them together? i plugged it in and it lit up for a while but then went out but I don't really know how the modem is supposed to work if there's no internet connected to it.
- first! are you sure the modem needs 12 V DC and not 12 V AC? Mine uses AC. OK, you can use a 12.5V in a 12V modem - the extra .5V is not a problem... Next, make sure the polarity is correct!! center pin is the correct polarity? If not, POOF! You will let the smoke out. Have you considered that the modem is bad and the power supply is not the problem here. If the modem is bad, you may have killed the supply you plugged in.
- Q: I want to switch to cable phone (indeed, that Triple play service offered by companies as Optimum or Time Warner). When power fails, you dont?expect to have Cable TV or internet, but phone service is different. You really need it all the time. Some people told me outages affect cable phone service. I?m very concerned because some neighborhoods in my city have had blackouts recently.
- I specifically put that question to my cable provider a few months ago. This was the official answer Quoted: ----------------------- Hello Jeff. Thank you for your email. The answer to your query is surrounded by a few variables, the main one being your proximity to the ‘node’ that your Internet service feeds off. In the event of a neighbourhood-wide power outage, our “nodes” are equipped by back-up batteries that may be able to supply the required signals for the modem to receive and transmit, though limited in duration. But as with any supposedly fool-proof system, there always exists the possibility of fortuitous failure. Please let us know if we can be of further assistance. Bob. Rep. no. 2597. E-Services Calgary, Telephone: 310-SHAW, Shaw Communications Inc. --------------------- So, in short, they do have battery backup for Internet on the local nodes... but for how long it will last is unknown and not guaranteed. That said, I am currently only using cable Internet to transport my VoIP services. I pulled the plug on my local telco, months ago. I have my cable modem, router, VoIP ATA adapter, and cordless phones connected to a battery-backed-up UPS power supply. But, these are all only temporary backup solutions. If you feel too nervous about not having phone or 911 service during a power outage... then, don't do it. Or, get a cell as your emergency backup comms.
- Q: I installed a new Power supply after my old one stopped working. I bought a Thermaltake TR2 500W. I connected everything that needed to be connected but it would not turn on. Then i disconnected the 4pin cable that goes to the motherboard, and it turned on. But my monitor didn't detect anything so it just went into quot;sleep modequot;. So every time i connect the 4 pin PCI-E connection to the motherboard it just doesn't turn on. Please help
- You might have a DOA power supply or motherboard. It might just have problems with the connections. Sounds like the problem is the motherboard if 2 power supplies dont work on it. I would consider getting a new motherboard.
- Q: Wire and cable should be used in parallel when the attention
- The former bv4 square copper wire is a single strand of hard copper wire, the latter BV4 square copper wire is multi-strand soft copper wire. Core (coredwire), with steel sheath for the outer tube filled with iron alloy powder to do core material, cross-section for the circular or rectangular line body. Also known as cored wire. It is used as a steel-making furnace outside the refining of the feed method to add refining agent and alloying agent. Can be directly added to the deep steel, the molten steel for deoxidation, desulfurization, degassing and non-metallic inclusions denatured treatment, to eliminate the aluminum deoxidized steel in the continuous casting steel | iron when the nozzle plugging the problem. As the deep addition of alloying elements in the molten steel, so the alloying element recovery rate is high and stable, the steel components can be fine-tuned to the best range. The reproducibility of the results is good.
