Some failures are part of the normal wear-and-tear of components in a system.
A basic principle in troubleshooting is to start from the simplest and most probable possible problems first. This is illustrated by the old saying "When you see hoof prints, look for horses, not zebras", or to use another maxim , use the KISS principle. This principle results in the common complaint about help desks or manuals, that they sometimes first ask: "Is it plugged in and does that receptacle have power? A troubleshooter could check each component in a system one by one, substituting known good components for each potentially suspect one.
However, this process of "serial substitution" can be considered degenerate when components are substituted without regard to a hypothesis concerning how their failure could result in the symptoms being diagnosed.
Simple and intermediate systems are characterized by lists or trees of dependencies among their components or subsystems. More complex systems contain cyclical dependencies or interactions feedback loops. Such systems are less amenable to "bisection" troubleshooting techniques. It also helps to start from a known good state, the best example being a computer reboot.
A cognitive walkthrough is also a good thing to try. Comprehensive documentation produced by proficient technical writers is very helpful, especially if it provides a theory of operation for the subject device or system.

A common cause of problems is bad design , for example bad human factors design, where a device could be inserted backward or upside down due to the lack of an appropriate forcing function behavior-shaping constraint , or a lack of error-tolerant design. This is especially bad if accompanied by habituation , where the user just doesn't notice the incorrect usage, for instance if two parts have different functions but share a common case so that it is not apparent on a casual inspection which part is being used.
Troubleshooting can also take the form of a systematic checklist , troubleshooting procedure , flowchart or table that is made before a problem occurs. Developing troubleshooting procedures in advance allows sufficient thought about the steps to take in troubleshooting and organizing the troubleshooting into the most efficient troubleshooting process. Troubleshooting tables can be computerized to make them more efficient for users.
Some computerized troubleshooting services such as Primefax, later renamed MaxServ , immediately show the top 10 solutions with the highest probability of fixing the underlying problem. With the help of injector pressure we can calculate the amount of fuel needed, through the following formula: Est. Horsepower x B.
Answer : In case of cars the torque is applied to the rear wheels, thus limiting accelerator due to front wheel drive due to weight transfer. This drive is bolted to the chassis of the car. Modern manufacturers therefore design rear wheel drive to have similar handling to front wheel drive wherever possible via suspension tuning.

In a tractor the pressure is same, so the force given by the liquid to the surrounding is equal to the pressure X area. Question 7. Answer : Tyres colour is black due to the proportion of carbon mixed in it during the vulcanization of the rubber, to make the tyre shear resistant.
Without vulcanization tyres won't be able to bear the friction heat and stress of the road. Thus carbon is responsible for giving tyres the prominent black colour. Adding of carbon prevents tyres from rapidly deteriorating because when ozone combines with the ultraviolet light from the sun. It attacks the polymer of the tyre. Question 8.
