The tyre load index (LI) on a passenger-car tire is a two- or three-digit numerical code used to cross-reference a load & inflation table that will give the maximum load each tire can carry at a given pressure. The load index is sometimes used in conjunction with the load range, which appears elsewhere on the tire.
Portable stereoscopic rangefinder from WWII The coincidence rangefinder of the Polish destroyer ORP Wicher Laser rangefinder Second World War German range finding tower at La Corbière Jersey A rangefinder (also rangefinding telemeter , depending on the context) is a device used to measure distances to remote objects.
The degree of rotation of the compensator determines the range to the target by simple triangulation. [1] Coincidence rangefinders made by Barr and Stroud used two eyepieces, and may be confused with stereoscopic units. The second eyepiece showed the operator a range scale so the user could range and read the range scale simultaneously. [2] [3]
For passenger and light truck tyres, the manufacturers or importers have the choice of either putting a sticker on the tyre tread or a label accompanying each delivery of batch of tyres to the dealer and to the end consumer. The tyre label will use a classification from the best (green category "A") to the worst performance (red category "G").
Stadiametric rangefinding, or the stadia method, is a technique of measuring distances with a telescopic instrument.The term stadia comes from a Greek unit of length Stadion (equal to 600 Greek feet, pous) which was the typical length of a sports stadium of the time.
A long-range laser rangefinder is capable of measuring distance up to 20 km; mounted on a tripod with an angular mount. The resulting system also provides azimuth and elevation measurements. A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object.
To solve this problem, the British [1] and U.S. militaries tested the use of large landscape paintings showing distant sites for range-finding and target-sighting in indoor gun ranges. [2] These so-called range-finder paintings proved so successful that a program was organized in the United States to produce them in larger numbers. [2]
A stadimeter operator adjusts the lower knob until the top and bottom of the object are aligned, and then reads the corresponding range off the edge of the lower knob through a small magnifying lens. A stadimeter is an optical device for estimating the range to an object of known height by measuring the angle between the top and bottom of the ...
