An 8m steel tape was purchased and advertised as follows: Standard temperature : 24°C Standard Pull : 7.5kgs Tape weight : 0.60 kgs Cross sectional area : 0.049 sq.cm. A survey team was required to lay out a rectangular field office measuring 9.5m x 4.75m in the following field conditions: Ambient field temperature : 40°C Actual pull : 13.2kg In addition, the tape was supported on both ends and at midspan during all measurements.

Question
An 8m steel tape was purchased and advertised as follows:
Standard temperature : 24°C
Standard Pull : 7.5kgs
Tape weight : 0.60 kgs
Cross sectional area : 0.049 sq.cm.
A survey team was required to lay out a rectangular field office
measuring 9.5m x 4.75m in the following field conditions:
Ambient field temperature : 40°C
Actual pull : 13.2kg
In addition, the tape was supported on both ends and at midspan
during all measurements.
** The modulus of elasticity of the tape is 2.03x106 kg/sqcm and the coefficient
of thermal expansion is 0.0000116m/°C (25 pts)
Answer the following: **Answers for corrections should be in 3
significant figures. ex. (1.23x10-4)
Length for laying out
a) Correction due to Temperature?
b) Correction due to pull?
c) Correction due to Sag?
d) Corrected Length to be laid out?
