This means the telescope component brings things visually 30 times closer. Many theodolites used by various government agencies used to be pro-rated at 25X more than adequate for most tasks including trackint weather balloons- this being called a Pibal ( Pilot-Balloon) theodolite. the term pilot is somewhat misleading, as it is not a manned and controlled ( hence piloted) vehicle but an unmanned balloon that, of course follows the wind currents aloft- and moves at the same rate and direction! These instruments, while rivalled by more modern gadgetry- are still used by the Weather bureau and particularily at airports and similar sites where wind functions are important to safe operation of aircraft. I understand some modern Theodolites are l00X ( for building surveying work)- but this might be a misunderstanding with the standard Focus of l00 feet- like the various fixed focusing stops on a camera. all theodolites have adjustable focusing, in part to adapt the instrument to different lightint conditions brought about by- you guessed it, the weather ( more sophisticated one might say diminution of light caused by atmospheric refraction, switch up the lens power!
5 mm is the least count of theodolite.
least count of theodolite is 1 second
A theodolite is a survey instrument. A tachometer tells you how many Revs per minute an engine is turning.
The Mechanical Parts are the objective lenses, Fine Adjustment, Coarse Adjustment, some of the microscopes can move the stage, and some microscopes can move the adjustable mirror... Hope I can HELP!
you must multiply the two lenses getting a total of 150X
It is clearly 450 because 15 times 30 is 450
Father of Theodolite
Transit and non-transit theodolite.
advantage and disadvantage of theodolite
30x = 30,000
Theodolite light is the correct spelling
principle of theodolite is based on the principle of trigonometry.
0.75 mm way to get this answer........... (diameter of field A X total magnification of field A) / total magnification of field B so start by finding the diameter of field A= which is the 1.5 next figure out what the total magnification of field A is= 150 (you get this answer by multiplying the ocular # which is 10x by the objective # which is 15x. (10 x 15= 150) next figure out what the total magnification of field B is =300 (you get this answer by multiplying the ocular # which is 10x by the other higher objective # which is 30x. (10 x 30 = 300) then you can use the formula and plug in all the answers you got to get the answer (1.5mm x 150)/300=.75mm
The principle of theodolite survey involves using a theodolite, a precision instrument with a rotating telescope, to measure horizontal and vertical angles in surveying and construction. By sighting through the telescope at specific points, surveyors can determine the angles and distances between objects, enabling accurate mapping and layout of land and structures. This tool is essential for precise measurements and alignment in construction projects.
