(P_f - P_s)/AE is the correction formula for____in which A represents_____and E represents____. W ln/24pf^2 is the correction formula for____, in which W represents_____and Pf represents____ In an N - sided geometrically closed traverse, the sum of the adjusted interior angles should add to______.Explanation / Answer
Fill in the blanks.
1. Varying Pull applied to the Tape. Reason: Random errors are those, whose cause is not known, so they can not be corrected, except using the mean or standard deviation. When tape is held in hand, the applied pull is not measured, sometimes the surveyor may apply large pull sometimes small pull, but it is not measured. Therefore, this error can be corrected only by taking multiple readings and by averaging.
2. Thermal expansion/contraction due to Temperature changes.
3. The wrong input of air pressure or density, which varies with temperature or elevation.
4. Pull Correction.; A represents the area of cross of the tape,; E is the young's modulus of elasticity of the tape material.
5. for Sag correction. ; W is the self weight of the tape; and Pf represents the applied pull.
6. should add to (2N-4)*90 degrees.
