6. INCLINED STADIA SIGHTS. A transit with an internal focusing telescope is used for stadia measurements. When the road reading at the horizontal hair was made equal to the height of instrument, the vertical angle observed for a certain measurement was +22°14'. If the stadia intercept was 1.25m and the stadia interval factor of the instrument used is 100, determine the horizontal distance from the transit to the rod and the difference in elevation between the point over which the transit was set up and the point in which the rod was held.
The following data were taken from the peg method of adjustment. Instrument at 1 Instrument at 2 Rod rdg. on A 4 m 3.7 m Rod rdg. on B 2 m 1.5 m Point 1 is midway between A and B. Point 2 is 20 m to the left of A, 120 m from B. 1. Determine the magnitude of the true difference in elevation between A and B. 2. Determine the correct rod reading at A for horizontal sight if the instrument is set up at point 2.
Subject : Surveying Give me both solutions other wise leave it. Please show the both solutions and choose the correct answer. Please answer all of these. Thank you
An externally focusing instrument was set up on the horizontal line between two points A and B. The following readings were observed: Rod Position Upper (m) Middle (m) Lower (m) θ (deg) A 1.546 1.865 1.517 9.3 B 1.589 1.784 1.858 9.2 The given angles were measured from the horizontal. If the stadia interval factor is 99.46, determine the horizontal distance (m) from A to B. Round your answer to 3 decimal places.
Problem
In the two-peg of a dummy level, the following observation are taken. INSTRUMENT SET UP NEAR INSTRUMENT SET UP NEAR А В Rod Reading on A 0.921 0.367 Rod Reading on B 1.430 0.768 a. What is the difference in elevation between A and B? Answer: b. If the line of sight is not in adjustment, determine the correct rod reading on B with the instrument still set up at A. Answer:
B and C were observed from point A where the instrument was set up at a height of 1.25m. Point B and C were ahead of point A. Below shows the data recorded as observed for points B and C. a. find stadia constant b. find the slope distance between the telescope at point A and rod reasiny at point B. c. find the difference in elevation between between B and C.
Any surveying instrument may be employed in stadia leveling as long as it can be used to measure vertical angles and is equipped with the standard cross hairs and a. an erecting eyepiece b. a compensator c. an inverting eyepiece d. stadia hairs

In the two-peg of a dummy level, the following observation are taken. Rod Reading on A Rod Reading on B INSTRUMENT SET UP NEAR A 3.463 0.821 INSTRUMENT SET UP NEAR B 4.125 1.307 What is the difference in elevation between A and B? If the line of sight is not in adjustment, determine the correct rod reading on A with the instrument still set up at B. If the line of sight is not in adjustment, determine the correct rod reading on B with the instrument still set up at A.
Fundamentals of surveying
The upper and lower stadia hair readings on a stadia rod held at station B were observedas 3.50 and 1.00m respectively, with the use of a transit with an interval focusingtelescope and having a stadia interval factor of 99.5. The height of the instrument abovestation A is 1.45m and the rod reading is taken at 2.25m. If the vertical angle observed is-23034’, determine the following:a. Inclined stadia distanceb. Difference in elevation between the two stationsc. The elevation of station B, if the elevation of station A is 155.54m above mean sealevel.
