Question

A line is regarded as 485 m long. It is measured with a 500 grams tape which is 30.05 m long at 20°C under a 4.5 kg pull supported throughout its length. During measurement the temperature is 4.5°C and the tape is suspended under a 6.5 Kg pull. The line is measured at 3% grade. What is the true horizontal distance?

◦E=2x10⁶ kg/cm²

◦v =126.54 cm³/kg

Given:
Nominal Tape Length	L₁
Total weight of tape	W
Standard Temperature of Tape	T₁
Temperature during measurement	T₂
Standard Pull of Tape	P₁
Pull applied during measurement	P₂
Measured Distance	Di
correction due incorrect tape length	Ci
Ground slope	S
Cross-sectional area of the tape	A

Solution
correction per tape length (correction per 30-m length)
incorrect tape length	C_I	Question Blank 11 of 20 meter
