Question
Show complete solution on Length for laying out, and Width for laying out.
Width 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:
Transcribed Image Text:Width 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:
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 2.03x10^6 kg/sqcm and the coefficient of thermal expansion is 0.0000116m/°C Answer the following: Effect field conditions on Tape a) What is the effect of temperature on the tape? (Too Long or To0 Short)?: b) What is the effect of pull on the tape? (Too Long or Too Short)?: c) What is the effect of sag on the tape? (Too Long or Too Short)?: 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:
