It is required to layout on the ground a rectangular lot 505.20 m long and 251.70 m wide. The tape to be used is exactly 100 m at 10 kg pull at 28 degrees celcius temperature. If the actual fieldword will be done at temperature 50 degrees celcius and the applied pull is 10 kg, what is the corrected area if the coefficient of thermal expansion for the tape is 0.0000116 per degrees celcius.
A 50m steel tape is of standard length at 25° C. If the coefficient of thermal expansion of steel is 0.0000115/° C. Determine the distance to be laid- out using this tape to establish two points exactly 1547.50m apart when the temperature is 33° C.
A steel tape of nominal length 30m was suspended between supports to measure the length of a line. The measured length of the line on slope of angle 30 50’ is 29.859m. The mean temperature during the measurement was 120c and the pull applied was 100N.

A 100 m. steel tape standardized at 20°C had a length of 100.600 m. It was used to measure a line A to B on tance was 622.70 m. The temperature at the time of measurement being 29° C. The stadia distance for the stme line was only 560.00 meters. Upon investigations the discrepancy was found out to be due to the fact that a 10 meter length (bet- ween 75-m. and 85-m.) was cut off. a) What is the true length of the sloping line? b) What is the horizontal distance of the same line if the difference of elevation between A and B is 0.72 meters?
A steel tape having a correct length at 22 degree Celsius was used to measure a base line and the recorded readings gave the total of 856.815m. I fthe average temperature during measurement was 18 degree Celsius, determine the correct length of the line.
