Tachymetre

More Examples:

Suppose you wanted to measure the speed of a jet airplane. After traveling 10 kilometers, you noted that 40

seconds had elapsed. The TACHYMETRE dial displays 90, but you traveled 10 kilometers, so the answer

would be 10 times that, or 900 km/hour.

You can also measure other things, like fuel consumption. Suppose a pound of fuel took 48 seconds to

burn. The chronograph second hand indicates on the TACHYMETRE dial that you are burning 75 pounds of

fuel per hour.

timed for 30 seconds produces 72 parts. Stopped at

the 30-second mark, the chronograph second hand

points to 120 on the TACHYMETRE scale; the

production rate of the machine is 120 x 72, or 8,640

parts per hour.

Example No. 4 – A manufacturing production line

Example No. 3 – A copier makes 10 copies in 45

seconds. The sweep second hand was thus stopped

at the 45-second mark, which coincides with the

figure 80 on the TACHYMETRE scale. The hourly

rate of this copier is 80 x 10, or 800 copies.

NOTE - The scale is valid for elapsed times from seconds to seconds. If the duration of the event is

outside this range, then the answer on the dial is not valid. Short durations of under eight seconds can be

extremely difficult to time accurately. Some of the following examples show ways to get around this limitation.
