8.9 SUBTENSE BAR Subtense method is an indirect method of distance
determination. This method essentially consists of measuring the angle
subtended by two ends of a horizontal rod of fixed length, called a subtense bar.

Construction Measurements
Subtense Triangulation From an understanding of subtense measurement, we
might reason to the use of a bar longer than 2 m, say a "bar" of 300 ft laid out by
taping or by subtense, and setting targets for sighting across a river. The principle
is ...

Essential Optics Review for the Boards
The image has a larger angular subtense than the original object; therefore, the
objects appear larger when seen through this optical system even though the
virtual image is smaller than the object. Angular magnification is the ratio of the ...

Alak De. c second observation 6 being greater than 3°, D = — cot a has to be
used. In the second observation D = 19.6 m, and such a small distance does not
justify the use of subtense measurement. Such measurements justify only in case
of ...
