7. Using the scale The dial is mainly used to compute an average speed after noting how long it takes to travel a fixed distance (like one mile or one kilometer), but it can also be used to compute many other things. The dial is a logarithmic scale that uses this formula to compute: DIL = 0 / Elapsed Time In Seconds The chronograph second hand indicates /, /, /2,,, 0 or,000 etc. units (miles, objects, pounds etc.). When stopped, the second hand points to the number on the scale by which the number of units (,, 0 or,000 etc.) must be multiplied to obtain per-hour production rate or per-hour speed. STRT/STOP STRT/STOP 2 0 0 METER S 0 2 0 0 M ETER S 0 Example No. car covers one mile in seconds. The second hand, stopped as the mile marker is passed, reads 0 on the scale. verage speed of the car is 0 x, or 0 miles per hour. lthough decimal units (0 liters, mile, kilometers) make computing simple, in practice, the scale can be used to calculate velocities and production rates from any number of units. Example No. 2 To measuring something much slower, such as a bicycle, you must use a shorter distance because the elapsed time must fall within the 7.2-0 second range. For this example, it took 3 seconds for a cyclist to travel / of a mile. Reading the dial displays a speed of 0mph, but the cyclist only traveled / of a mile, so the actual speed would be / of that or an average speed of 25mph over the quarter mile.
Tachymeter 8. NOTE - The scale is valid for all elapsed times from 7.2 seconds to 0 seconds. If the duration of the event is outside this range, then the answer on the dial is not valid. Some of the following examples show ways to get around this limitation. STRT/STOP STRT/STOP 2 0 0 METER S 0 2 0 0 M ETER S 0 Example No. 3 copier makes copies in 5 seconds. The sweep second hand was thus stopped at the 5-second mark, which coincides with the figure 80 on the scale. The hourly rate of this copier is 80 x, or 800 copies. Example No. manufacturing production line timed for seconds produces 72 parts. Stopped at the -second mark, the chronograph second hand points to 0 on the scale; the production rate of the machine is 0 x 72, or 8,0 parts per hour. More Examples: Suppose you wanted to measure the speed of a jet airplane. fter traveling kilometers, you noted that 0 seconds had elapsed. The dial displays 90, but you traveled kilometers, so the answer would be times that, or 900 km/hour. You can also measure other things, like fuel consumption. Suppose a pound of fuel took 8 seconds to burn. The chronograph second hand indicates on the dial that you are burning 75 pounds of fuel per hour.
Miscellaneous 9. t 8 F (20 C), sound travels at 3m or 37yds /,9ft per second in air at sea level. Therefore, at 8 F (20 C) sound will travel: mile (,70 yards / 5,280 feet) in.8 seconds,000 yards in 2. seconds kilometer in 2.9 seconds To estimate the distance to an event (such as an explosion, muzzle flash, lightning, etc.), measure the time from the visual flash to the sound and multiply the seconds by the per second speed. For example the measured lightning to thunder time at 8 F is seconds. x 3m or 37yds /,9ft would produce 3,0m or 3,70yds /,290ft. (2.miles) lternately, you can divide the measured time at 8 F by.8 to get miles (s /.8 = 2.miles), or 2. for thousand yard distance, or by 2.9 for kilometers. NOTE: t 32 F (0 C), sound travels at 332m or 33yds /,089ft per second in air at sea level. Therefore, at 32 F (0 C) sound will travel: mile /,70 yards / 5,280 feet in.85 seconds,000 yards in 2.75 seconds kilometer in 3.0 seconds 0 2 00 METER S Example: Sea level temp is 8 F and lightning to thunder measured time is 7. seconds. Distance of lightning strike point is: 7.s x,9ft = 9,ft 7.s x 37yds =,52yds 7.s x 3m = 5,98meters OR: 7.s /.8s = 3.72 miles 7.s / 2.s =.5 thousand yards 7.s / 2.9s = 5.98 kilometers
