A 30-m steel tape is of standard length at 20°C with a pull of 55N. A rectangle is measured with this tape. The sides are recorded as 144.95 m and 113 m. The average temperature during the measurement is 30°C with a pull of 55N. Use coefficient of expansion of steel tape as a 0.0000116/°C. a. Compute the actual length of tape during measurement. b. What is the true area? c. What is the error in area in square meters? A 30-m steel tape is of standard length at 20°C with a pull of 55N. A rectangle is measured with this tape.
