It is better to drive your car at a stretch rather than driving for a little distance every day. This simple formula can help you monitor the mileage to manage your traveling expenses. Displacement is defined as the change of position. However, the odometer is all about monitoring the distance a vehicle has been driven for i. However, displacement is simply a change in position from point A to point B. It is value displayed in the odometer which a buyer looks for to make a final decision.
Your car is a machine, components of which go through a lot of wear and tear. The average life of most of the car components is dependent upon the distance a car has covered. Be it the car parts or the overall appeal, it is the value displayed on the odometer which is taken into consideration to determine the final selling price.
Online automobile marketplace such as Droom with their Orange Book Value tool takes in the kilometers a car has been driven for to generate a fair market price of a vehicle. Now, that you are aware of everything pertaining to odometer, make sure you help your peers understand its use an importance. Your email address will not be published.

Key points: For what purpose Odometer is used in vehicle? What is the difference between odometer and mileage? What is the difference between speedometer and odometer? Can the odometer be reset?
How do you calculate mileage with an odometer? For what purpose Odometer is used in vehicle? The resale value of a car The Kilometers a car has traveled for is one of the most important factors which go into deciding its resale value. Fuel consumption You can reset the days reading to evaluate the car fuel efficiency. The original odometer is a precision mechanical device incorporating a set of gears and a series of numbered tumblers.
With every 10 turns, the mechanical links rotate the adjacent tumbler by one digit, and so on. The most basic odometers show up to six digits including one decimal place, which means the readout is reset to zero after 99, Soon enough, car manufacturers supplemented the odometer with a four-digit tripmeter that could be manually reset, added another digit to the odo display so it could read up to , None of these improvements, however, incorporated any fraud-deterrent feature.
Technically, it could be clocked back to any mileage figure. Even driving the vehicle in reverse can do the trick. The cable usually spins inside a protective metal tube with a rubber housing.
On a bicycle , a little wheel rolling against the bike wheel turns the cable, and the gear ratio on the odometer has to be calibrated to the size of this small wheel.
On a car , a gear engages the output shaft of the transmission , turning the cable. The cable snakes its way up to the instrument panel, where it is connected to the input shaft of the odometer. This odometer uses a series of three worm gears to achieve its gear reduction. The input shaft drives the first worm, which drives a gear. Each full revolution of the worm only turns the gear one tooth. That gear turns another worm, which turns another gear, which turns the last worm and finally the last gear, which is hooked up to the tenth-of-a-mile indicator.
Each indicator has a row of pegs sticking out of one side, and a single set of two pegs on the other side. When the set of two pegs comes around to the white plastic gears, one of the teeth falls in between the pegs and turns with the indicator until the pegs pass. This gear also engages one of the pegs on the next bigger indicator, turning it a tenth of a revolution.
You can now see why, when your odometer "rolls over" a large number of digits say from 19, to 20, miles , the "2" at the far left side of the display may not line up perfectly with the rest of the digits.
A tiny amount of gear lash in the white helper gears prevents perfect alignment of all the digits. Usually, the display will have to get to 21, miles before the digits line up well again. You can also see that mechanical odometers like this one are rewindable. When you run the car in reverse, the odometer actually can go backwards -- it's just a gear train.
In the movie " Ferris Bueller's Day Off ," in the scene where they have the car up on blocks with the wheels spinning in reverse -- that should've worked! In real life, the odometer would've turned back. Another trick is to hook the odometer's cable up to a drill and run it backwards to rewind the miles. While that does work on older mechanical odometers, it does not work on the new electronic ones, as we will see in the next section If you make a trip to the bike shop, you most likely won't find any cable-driven odometers or speedometers.
Instead, you will find bicycle computers. Bicycles with computers like these have a magnet attached to one of the wheels and a pickup attached to the frame. Once per revolution of the wheel, the magnet passes by the pickup, generating a voltage in the pickup.
