This formula uses 1 Functions, 5 Variables
Functions Used
sin - Sine is a trigonometric function that describes the ratio of the length of the opposite side of a right triangle to the length of the hypotenuse., sin(Angle)
Variables Used
Vertical Distance - (Measured in Meter) - vertical Distance between center of transit and point on rod intersected by middle horizontal crosshair.
Staff Intercept - (Measured in Meter) - Staff intercept is the difference in reading between top and bottom cross hairs.
Vertical Angle - (Measured in Radian) - Vertical Angle is the angle between horizontal distance and slope distance.
Revolution of Screw - Revolution of screw is the number of revolutions made for the micrometer screw.
Distance in One Turn - (Measured in Meter) - Distance in One Turn is the distance by which the line of sight moves by one revolution of the screw.
STEP 1: Convert Input(s) to Base Unit
Staff Intercept: 3 Meter --> 3 Meter No Conversion Required

What is Gradienter?

It is mainly used in setting out gradients, but is also used in tacheometry. When the tangent screw actuating the vertical circle of a theodolite is provided with a micrometer head and a scale for counting the whole turns by which it has been turned, it is called gradienter. The pitch of the screw is kept such that when moved by one revolution, the line of sight moves by tan–1 0.01.

What is Tangential Method?

In this method, stadia hairs are not used to bisect the staff for observations. Two vanes at a constant distance apart are fixed on the staff. Each vane is bisected by the cross-hair and the staff reading and vertical angle corresponding to each vane are recorded. This method is preferred when the telescope is not equipped with a stadia diaphragm.
