Staff Intercept in Gradienter given Horizontal Distance Solution

STEP 0: Pre-Calculation Summary

Formula Used

Staff Intercept = Distance between Two Points/((100*cos(Vertical Angle)^2*0.5*sin(2*Vertical Angle))/(Revolution of Screw*Distance in One Turn))
s_i = D/((100*cos(x)^2*0.5*sin(2*x))/(m*c))
This formula uses 2 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)
cos - Cosine of an angle is the ratio of the side adjacent to the angle to the hypotenuse of the triangle., cos(Angle)

Variables Used

Staff Intercept - (Measured in Meter) - Staff intercept is the difference in reading between top and bottom cross hairs.
Distance between Two Points - (Measured in Meter) - Distance between Two Points is defined as the length of space between two points. For finding the distance when curvature effects are considered, the value must be considered in kilometres.
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

Distance between Two Points: 35.5 Meter --> 35.5 Meter No Conversion Required
Vertical Angle: 20 Degree --> 0.3490658503988 Radian (Check conversion here)
Revolution of Screw: 3.1 --> No Conversion Required
Distance in One Turn: 2.5 Meter --> 2.5 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

s_i = D/((100*cos(x)^2*0.5*sin(2*x))/(m*c)) --> 35.5/((100*cos(0.3490658503988)^2*0.5*sin(2*0.3490658503988))/(3.1*2.5))

Evaluating ... ...

s_i = 9.69439969719227

STEP 3: Convert Result to Output's Unit

9.69439969719227 Meter --> No Conversion Required

FINAL ANSWER

9.69439969719227 ≈ 9.6944 Meter <-- Staff Intercept

Vertical Distance between Center of Transit and Rod Intersected by Middle Horizontal Crosshair

LaTeX Go Vertical Distance = 1/(2*((Stadia Factor*Rod Intercept*sin(2*Vertical Inclination of Line of Sight))+(Instrument Constant*sin(Vertical Inclination of Line of Sight))))

Horizontal Distance between Center of Transit and Rod

LaTeX Go Horizontal Distance = (Stadia Factor*Rod Intercept*(cos(Vertical Inclination of Line of Sight))^2)+(Instrument Constant*cos(Vertical Inclination of Line of Sight))

Stadia Distance from Instrument Spindle to Rod

LaTeX Go Stadia Distance = Intercept on Rod*((Focal Length of Telescope/Rod Intercept)+Stadia Constant)

Additive Constant or Stadia Constant

LaTeX Go Stadia Constant = (Focal Length of Telescope+Distance from Center)

What Equipment is needed to Measure Staff Intercept in Gradienter given Horizontal Distance?

The equipment needed to measure Staff Intercept in Gradienter given Horizontal Distance includes a leveling instrument such as a gradienter, a leveling rod, and a measuring tape.

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.
