Step by step
Solved in 2 steps
- What are the problems faced by the incorrect lengths of tape?A 30 m. steel tape is 2 mm too long at 20°€. A rectangle is measured with this tape. The sides are recorded as 114.95m and 113.00 m. The average temperature during the measurement is 30°C and k = 11.6 x10^-6/C a.)Compute the actual length of tape during measurement. b.)What is the true area of the lot?An 8m steel tape was purchased and advertised as follows: Standard temperature : 24°CStandard Pull : 7.5kgsTape weight : 0.60 kgsCross sectional area : 0.049 sq.cm.A survey team was required to lay out a rectangular field officemeasuring 9.5m x 4.75m in the following field conditions:Ambient field temperature : 40°CActual pull : 13.2kgIn addition, the tape was supported on both ends and at midspanduring all measurements.** The modulus of elasticity of the tape is 2.03x106 kg/sqcm and the coefficientof thermal expansion is 0.0000116m/°C (25 pts)Answer the following: **Answers for corrections should be in 3significant figures. ex.
