Sag Correction between Points of Support Solution

STEP 0: Pre-Calculation Summary

Formula Used

Sag Correction = -(Weight of Tape per Unit Length^2)*(Unsupported Length^3)/(24*Pull on Tape^2)
C_s = -(W^2)*(U_l^3)/(24*P^2)
This formula uses 4 Variables

Variables Used

Sag Correction - (Measured in Meter) - Sag Correction is the adjustment of optical elements to counteract deformation, maintaining proper shape for optimal performance in imaging systems.
Weight of Tape per Unit Length - (Measured in Kilogram per Meter) - Weight of Tape per Unit Length is a measurement used in surveying to determine weight of measuring tape over a certain distance and is used to calculate tension and sag of tape during measurements.
Unsupported Length - (Measured in Meter) - Unsupported Length is the span or distance between supports or points of restraint for a structural member, such as a beam or a column.
Pull on Tape - (Measured in Newton) - Pull on Tape is the tension or pull applied to the tape in newtons (N).

STEP 1: Convert Input(s) to Base Unit

Weight of Tape per Unit Length: 3 Kilogram per Meter --> 3 Kilogram per Meter No Conversion Required
Unsupported Length: 9 Meter --> 9 Meter No Conversion Required
Pull on Tape: 8 Newton --> 8 Newton No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

C_s = -(W^2)*(U_l^3)/(24*P^2) --> -(3^2)*(9^3)/(24*8^2)

Evaluating ... ...

C_s = -4.271484375

STEP 3: Convert Result to Output's Unit

-4.271484375 Meter --> No Conversion Required

FINAL ANSWER

-4.271484375 ≈ -4.271484 Meter <-- Sag Correction

What is Sag Correction?

A tape correction applied to the apparent length of a level base line to counteract the sag in measuring tape (i.e., the difference between the horizontal distance between supports and the length measured along the curve.) The correction due to sag must be calculated separately for each unsupported stretch separately. Hence the correction is taken to be negative.

How does the Temperature Correction Affect the Accuracy of Surveying measurements?

Temperature correction can significantly affect the accuracy of surveying measurements. Without temperature correction, the measurements can be off by a few millimetres or even centimeters, depending on the temperature difference. By applying temperature correction, surveyors can ensure that their measurements are accurate and reliable.

How to Calculate Sag Correction between Points of Support?
