An 8m steel tape was purchased and advertised as follows: Standard temperature : 24°C Standard Pull:8.5kgs Tape weight : 0.70 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
