what exactly is odometer?

Answer 1

An odometer is a device used for indicating distance traveled by an automobile or other vehicle. It may be electronic or mechanical. The word derives from the Greek words hodós, meaning 'path' or 'way', and métron, 'measure'.

Mechanical odometers usually appear as a row of wheels with an edge of each wheel exposed to the driver. There are digits written on the edges of these wheels. A mask obscures these wheels from view, except for one row of digits which can be seen through a window in the mask.

On older cars, odometers could only indicate up to a value of 99,999. At 100,000, the odometer would restart from zero. This is known as odometer rollover. Newer cars usually have odometers that can indicate up to a value of 999,999.

A common form of fraud is to tamper with the reading on an odometer. This is done to make a car appear to have been driven less than it really has been, and thus increase its apparent market value. Many new cars sold today use digital odometers that store the mileage in the vehicle's engine control module making it theoretically possible to manipulate the mileage electronically. With mechanical odometers, the speedometer can be removed from the car dash board and the digits wound back, or the drive cable can be left disconnected while on the road (this also disables the speedometer).
An odometer for measuring distance is described by Vitruvius around 27 and 23 BC. The actual invention may have been by Archimedes during the First Punic War. Hero of Alexandria describes a similar device in chapter 34 of his Dioptra. The device was also invented in ancient China by Zhang Heng (78 – 139).

The odometer of Vitruvius was based on chariot wheels of 4 feet (1.2 m) diameter turning 400 times in one Roman mile (about 1400 m). For each revolution a pin on the axle engaged a 400 tooth cogwheel thus turning it one complete revolution per mile. This engaged another gear with holes along the circumference, where pebbles (calculus) were located, that were to drop one by one into a box. The distance travelled would thus be given simply by counting the number of pebbles. Whether this instrument was ever built at the time is disputed. Leonardo da Vinci tried to build it according to the description but failed. Later, Ben Franklin invented his own version. In modern times, however, Andre Sleeswyk was able to make a working model using gears similar to the Antikythera mechanism as opposed to the traditional cogwheel.

The odometer as used in most modern systems, where separate gears control each digit, was invented by William Clayton with help from Orson Pratt. Clayton, a Mormon Pioneer, developed the odometer (dubbed the "roadometer") to keep track of wheel revolutions on the pioneer wagons. The odometer had at least two gears, including one which turned every quarter-mile and one which turned every ten miles.

Answer 2

It is a tool of measurement used to determine how far a vehicle has traveled. Older, mechanical or analog style, odometers used a set of numbered wheels as a display. Newer vehicles use digital odometers. They are usually found in the speedometer of the vehicle which is located in the instrument panel behind the steering wheel. Under the odometer is usually a trip odometer. The trip odometer can be reset by the driver at any time back zero, so that the driver can measure the distance of a specific trip. The main odometer cannot be reset by the driver.

climate, like climate, describes the state of the ambience in words of elements which contain temperature, wind and rainfall. yet while climate describes circumstances as measured in hours, days or weeks, the elements is prevalent climatic circumstances measured over the lengthy time period: months, years or a lengthy time period. a minimum of it really is the way it really is continually defined. the reality is easily a tiny bit better complicated because climate also encompasses variability – case in factor, the frequency of extreme climate activities. the excellence between climate and climate is an important one. case in factor, climate forecasts will be fairly particular ("it's going to be moist tomorrow morning and chilly contained in the afternoon, with temperatures dipping on the purpose of freezing") yet are little use better than some days into the destiny. compared, climate predictions concentration on envisioned alterations in prevalent circumstances, at the same time as recognising that correct days, weeks, months or years will continually dollar the longer-time period style. each and each portion of the international has its own climate (and positively its own climate), although scientists also learn the planet's elementary climate equipment – case in factor by skill of monitoring the conventional international temperature. The time period climate comes from the Greek klinein, or "slope", describing how the attitude that the daylight hits the earth varies in diverse areas.

Answer 4

A piece of of equipment, usually found in the dashboard of a car that tracks mileage or distance travelled.

Answer 5
