Are mechanical or electrical components more reliable?
545355
A general rule of thumb I have heard in engineering is "the fewer moving parts the more reliable" (another conflicting rule is "if it ain't broke, it doesn't have enough features yet").\n\nI would say it depends on the application.  I know hard-drives inside computers or MP3 players are very sensitive mechanical components.  Then again, electrical hardware is prone to overheating.

mechanical engineers deals with machines to be more precise the moving parts of any machine while electrical engineers deal with the electrical circuitry o any machine. for example the gears of any machine will be under the purview of mechanical engineers while all the electrical on off switches are dealt by electrical engineers. In an air conditioner , the compressor willl be designed by mechanical engineers while electrical engineers wil design the temparature control circuits.

It depends on electrician

Depends where you are.....the best one where I live is where my cars were bought.\nThe big names were...............useless...lots of $$$ spent and couldn't even fix problems.....and placed faulty parts !!!!!!!

Hard Disk are not prone to failure so often.\n\nMostly malfunctions occur due to error in manufacturing stage \n\nthat is very minimal .\n\nMainly malfuctions are produced by improper connection with the Hard disk and socket wires \n\nMalfunction may occur due to excessive heat \n\none or more pins in the hard disk may be broken\n \n\nat the malfunction the pin count is checked and connection is made again\n\nplace hard disk in proper chamber and check whether the fan is running.\n\nDo not expose Hard disk to sunlight and excessive heat.\n\nif it continues do not tamper the hard disk

While Most people turn their computers on and off and put little to no thought towards it, the design of the components are geared for just that. Now to take it to one level up, almost all electronics over time will succumb to the expansion and shrinking associated with their normal operating temperatures. As components heat up, solder joints swell and expand, along with normal minute system vibrations, these solder joints and electronic components over time lose their connection solidity. Think of it this way, when does a light bulb blow out? it happens when you usually are turning it on, not when it has been up and running for awhile, your computer is the same, but don't worry, most computers wont reach the "Burn out" stage quickly, rather it is a long and arduous journey before your solder joints go on strike ;)

Over the ten years that we have purchased 20,000+ used laptops our techs have found IBM and Toshiba to be the most reliable and the easiest to work on.  I personally have been buying Toshiba laptop for fifteen years and have good luck with them.

Mechanical engineers build things that move, that deal with heat transfer and energy, power and work and things like that. Mechanicals would work on designing cars or amusement park rides or airplanes or ceiling fands or air conditioners.\n\nElectrical engineers deal with circuitry and electronics. They'd build a better digital clock or timer, or something like that.\n\nMechanicals might deal with electrical engineering in passing, since it's the broadest discipline. Electricals just focus on their one area of expertise.

I'd Trojan is the trusted brand. Not an expert, but Trojan definately has a variety and I can say that about 90% of Lifestyles broke.  Only had one Trojan break.

I think an assembled pc will always be better. You can change things as you want, you can upgrade as needed, warranty is per part and not per entire product, etc.

I think that many cars have the reputation for being extremely "reliable" when in reality they break as much as any other car does. Many Japanese companies offer longer warranties than other car manufacturers, so while their cars may break, they cover the repair costs, which improves customer satisfaction ratings. Every car make and model has its ups and downs; people adore Nissans, but I've seen several Nissans bought back by the company because of faulty manufacturing. My personal theory is to buy the car you like rather than one that's supposedly "more reliable."

"To take just one example, ISO standards for such seemingly humble items as bolts, nuts, screws, pins and rivets literally help stop much in the world around us from falling apart - but you're not likely to come across references to them in the business and economic press, nor see companies proudly advertising that they implement them."  \n\nTry the link below and take "The Magical Demystifying Tour of ISO 9000 "

i believe there is no specific answer to this question as it is very relative. It would depend on various factors most importantly the purpose of the device being designed and what could be the consequence of the failure. but it should be always greater than one.

honestly, in terms of today's technology, it really doesn't matter at all.  Many times, people are worried that keeping it on will wear out the components, and sometimes that turning it back on will shock the components too much.  If you're buying a new computer every 4-5 years, it really does not matter

Check RF cafe and quizzes under the site map. Also check out the free tests on ETA international these are geared for electronic technicians but should give a good review of fundamental electronic components. \n\nEnjoy.

I've bought hundreds of PCs over the years, including scores from Micron, Dell, HP/Compaq... even half a dozen e-machines.  My experience has been that Dell's support was excellent.  They overnighted the parts every single time (which was seldom since they build pretty good systems).  HP/Compaq-- constant headaches, multiple failures, terrible tech support.  Don't even consider an e-machine unless you're looking for a boat anchor.\nAs for Micron, I can't comment on their tech support.  I ran about 75 of their machines for three years.  I never once had a hardware failure.
