The length of a line measured with a 20 metre chain was found to be 250 metres. What is the true length of line if the chain was 10 cm too long
During the measurement of a line by chain or tape in slopes, if the length of line is ‘l’ and height difference between the ends of the line is ‘h’ then the correction to the measured length is more than h2/2l by

The required slope correction for a length of 60 m along a gradient of 1 in 20 is
A 30 m steel tape was standardized at 20°C and measurements of distances were taken at 15°C. if the coefficient of linear expansion α of the material of the tape were 0.000112 per °C, then error due to temperature per tape length would be
A 100 m tape is suspended between the ends under a pull of 200 N. The weight of the tape is 30 N. The correction for sag and correct distance between the tape ends is
Distance between two stations A and B can be precisely measured with one complete Gunter’s chain and one complete Engineer’s chain. The distance between A and B is
The downhill end of a 30 m tape is held 90 cm too low. What is the horizontal distance measured
The distance between the points measured along a slope is 428 m. If the angle of slope between the points is 8° than the horizontal distance between them is
A line of true length 500 m when measured by a 20 m tape is reported to be 502 m long. The correct length of the tape is
A 20 m chain was found to be 10 cm too long after chaining a distance of 2000 m. It was found to be 18 cm too long at the end of the day’s work after chaining a total distance of 4000 m. What is the true distance if the chain was correct before the commencement of the day’s work?
