PLEASE FIND SOLUTION THAT WILL COME UP WITH THE SAME ANSWER The two-peg test is used to determine if the line of sight of an engineer’s level is in adjustment, and the following rod readings are taken: with instrument set up near A, rod reading on A is 1.623 m, rod reading on B is 2.875 m; with instrument set up near B, rod reading on B is 1.622 m, and rod reading on A is 0.362 m. i. The correct rod reading on A to give a level line of sight with the instrument still set up near B should be? answer: 0.366 m ii. In order to adjust the line of sight, the horizontal cross hairs should be moved? answer: Upward by 0.004 m

I need a solution with clarification. engineering survey Q3) leveling staff setup on a BM of elevation of 89.90 m is observed from point A where the three staff reading are 1.00, 2.37, 3.75 m with a depression angle of 05° 32. Then the staff moved to point B where the three staff reading are(- 0.20, -1.88, -3.57) m with an elevation angle of 04 18. Compute the horizontal distance of B from A and reduced level of stations at B (assume stadia interval factor 100 and the additive constant of the instrument = 30).
While leveling across a river, the staves readings held at (R) and (S) from the instrument stationed at (P) and (Q) : Staff reading at R from P = 1.332m, Staff reading at S from P =1.016m Staff reading at R from Q =1.614m, Staff reading at S from Q =1.278m (R) and (Q) were close to each other on one bank of the river with (S) and (P) similarly situated on the other bank. If the elevation of (S) is (10. 376m) calculate the elevation of (R).

The negative reading was taken with the staff inverted from a point below a sunshade. Find the reduced levels of all the points if the first reading was to a BM of assumed RL 100.00.
Kindly answer this, this is in the surveying subject. Thankyou in advance have a nice day! (your explantion) -What is differential leveling? -What is Backsite and foresight?
(Alternate Peg Method) In the two-peg test of a dumpy level, the following observations are taken: Rod reading On point A On point B Instrument set-up near M (m) Instrument set-up near P (m) 0.296 1.563 0.910 2.140 Requirements: a. Determine the true difference in elevation between A and B. b. Determine the error in the line of sight for the net distance AB c. If the line of sight is not in adjustment, determine the correct rod reading on A with the instrument still set up near B.
Which of the following may cause errors in leveling measurement? (Multiple choice) (Multiple choice) 1 □ A. The level tripod sinks O B. Reading Error □ C. The instrument is not erected at approximately the same distance from front to back □D. Improper implementation of the centering of the level □ E. Subsidence occurred at the level where the level was erected □ F. Vertical dial error of the level
Surveying//Theoritical part.
A stadia measurement was undertaken with a theodolite having an internal focusing telescope and a stadia interval factor of 98.8. when a backsight was taken on a turning point whose elevation is 205.62m, the rod interval observed was 1.94m; and with the horizontal hairs set at 1.50m on the rod, the vertical angle reading was -13 45’. For a foresight to a control point, the rod intercept was 1.17m; and with the horizontal hair reading of 1.60m on the rod, the vertical angle observed was -15 30’. Determine the elevation of the line of sight at the instrument point and the elevation of the point on which the foresight was taken. SKETCH THE PROFILE PLEASE
A horizontal collimation test is performed on an automatic level following the procedures described in Section 4.15.5. With the instrument setup at point 1, the rodreading at A was 3.886 ft, and to B it was 3.907 ft. After moving and leveling the instrument at point 2, the rod reading to A was 4.094 ft and to B was 4.107 ft. What isthe collimation error of the instrument and the corrected reading to A from point 2?
