what does the odometer of an automobile measure

What does an odometer measure?

Odometer, or odograph , is a device that measures the distance travelled by an automobile based on the perimeter of the wheel as the wheel rotates. The odometer gives us only the measure but doesn’t show the direction of velocity. The odometer measures the scalar quantity – the speed of the car.

Does the odometer show the direction of velocity?

The odometer gives us only the measure but doesn’t show the direction of velocity. The odometer measures the scalar quantity – the speed of the car. The device may be electronic or mechanical or a combination of the two.

how does an odometer work

Mechanical odometers are turned by a flexible cable made from a tightly wound spring. 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.

Where is the odometer located on a car?

Beneath the steering wheel, on the dashboard, is the odometer which displays the distance a car has run for. Odometer reading comes in very handy if you are looking to sell your car or even to calculate the mileage.
