A stadia rod held at a distant point B is sighted by an instrument set up at A. The upper and lower stadia hair readings were observed as 1.205m and 0.875m, respectively. If the stadia interval factor (K) is 99.8, and the instrument constant (C) is 0.3m, determine the length of line AB in meters.
An angle APB is measured at different times using various instruments and procedures. The results, which are assigned certain weights, are as follows: 46-13-28, wt 1; 46-13-32, wt 2; 43-13-30, wt 3; and 43-13-32 , wt 4. What is the most probable value of the angle?
Can you pls help me understand how this is solve.. Topic: Tape corrections (Fundamental surveying) •pls answer with Complete Solution • 3 decimal places ALL answers 1. A Civil Engineer used a 50m tape in measuring an inclined distance. The measured length on the slope was recorded to be 528.368 m. long. The difference in elevation between the initial point and the end point was found to be 6.369 m. The 50m tape is of standard length at a temp. of 28degC and a pull of 8kg. During the measurement, the temperature reading was 35degC and tape was supported for a full-length with an applied pull of 12kg. Cross sectional area of tape is 0.03 sq. cm., weight of tape is 0.50kg. Determine the true horizontal distance. Thank you. I'll give your answer A LIKE for helping me with this..
A dumpy level with an internal focusing telescope was set up on the left bank of a river and the rod readings tabulated below were taken on a stadia rod held successively at the left and right water edges. If the stadia interval factor of the instrument is 100 and the stadia constant is 0.30m, determine the width of the river. Rod held at LWE: Upper Reading = 2.190 m & Lower Reading = 2.155 m Rod held at RWE: Upper Reading = 2.275 m & Lower Reading = 2.070 m
