Unit Conversion

Standard units are also called SI units. SI units are used for measuring a physical quantity satisfying certain conditions. There are two types of units: fundamental units and derived units. Fundamental units are physical quantities that are independent, that is, they do not depend on other quantities like mass, length, or time. There are plenty of quantities in our lives which need to be measured and compared. Measuring is the comparison of a particular physical quantity with its reference value. A unit is a measure of a fixed physical quantity. A physical quantity is the product of a unit and the numerical value we need to compare with.

Problem 5. A tacheometer with an external focusing telescope was set up to determine the difference in elevation of TP1 and TP2 having a stadia interval factor of 99.78 and stadia intercept reading of 2.47 at TP2 at a vertical angle of +7°25'. The height of instrument is 1.57 m and the middle reading at TP2 is equal to 2.32 m. a) Compute the difference in elevation of TP1 and TP2. b) Compute the horizontal distance between TP1 and TP2.

Distance between the two points Pand Q was required to be determined from tacheometer fitted with an anallactic lens (k = 100, C = 0). With the instrument at P and staff at Q, the observations made were a vertical angle of + 8°43' and staff intercept of 1.805 m held vertical. At a later stage, it was found that constants of the tacheometer were 100.5 and 0.7. What would be the percentage error in the computed distance PQ? %3D
A line of three-wire differential levels goes from benchmark Gloria to benchmark Carey. The length of the line was determined to be 2199 m. The instrument had a stated compensator accuracy of ±0.3″. The instrument-rod combination had an estimated reading error of ±1 mm per km. The instrument is found have a inclined collimation error of 1.0 mm per km so the sight distances were kept to approximately 50 ± 5 m. If the observed difference in elevation is 15.601 m, what is the estimated error in the final elevation difference?
ANSWER KEY:PROBLEM 5.11D=150.7275m∆h=33.8483m NOTE:Here is problem 5.10. A calibration was made to evaluate the constant of a transit with a focusing interval telescope. The transit was set to the end of line with a distance of 100m and at the other end, a staff was set with a stadia interval of 0.978m. Calculate the missing constant of the transit.
Questiore 1 The staff readings, taken with a tacheometer, are 0.850m, 1.170m, and 1.525 m. Determine the horizontal distance from the instrument station to staff if K=100 and C = 0.20m. If the RL. of instrument station is 101.5m and height of trunnion axis is 1.36m, then RL. of the staff station is
1. A tacheometer was set up at station P and observations were made to two stations Q and R. The vertical angles to Q and R were 5°30 and 1°08 respectively. The cross-hair readings at Q were 2.105, 2.47 and 2.835 and those at R were 2.215, 2.56 and 2.905. The staff were held vertical in both cases. The instrument constants were 100 and 0.3. The reading from P to a BM of RL 285.35m was 2.255. The horizontal angle QPR measured was 58°30. Find the distance QR, the gradient from Q to R and the RLs of Q and R.
In tacheometry survey, an intercept of 0.755m was recorded on a staff which was believed to vertical, and the vertical angle measured on the theodolite was +15º. Actually, the staff which was 4 metres long was 0.14m out of plumb bob and leaning backwards away from the instrument position. Assuming it was an anallatic instrument with a multiplying constant of 100, what would have been the error in the computed horizontal distance?
The following tacheometric observations were made from station A to stations 1 and 2. The height of the instrument above the ground was 1.52 m. Take stadia interval factor and constant as 100 and 0, respectively. If the staff was inclined by 1° to the vertical, solve for the following:a. Error in horizontal distance if the staff is inclined towards theinstrument for the line A-1. b. Error in the vertical distance if the staff is inclined away from theinstrument for the line A-2. c. If the elevation of point 1 is 115.673 m, determine the correctelevation of point 2.

A tilting level is set up halfway between points A and B and rod reading on both points are 1.969 and 2.161 m respectively. The level is then set up 1.50 m away from A along the extension of line AB and 53.50 from B. Then rod readings on A and B were recorded as 1.554 m and 1.728 m, respectively. Determine if the line of sight is inclined downward or upward and the amount by which the horizontal cross hair should be moved to adjust the line of sight.
