Chapter 2. Accuracy and Errors [SURVEYING Vol.1 by Dr. B. C. Punmia]Problem 5. An angle has been measured under different field conditions, with results as follows. Find (i) the probable error of single observation (ii) the probable error of the mean.
Book Solution Manual, Surveying vol.1 by Dr. B. C. Punmia. Chapter 3. Linear Measurements. [SURVEYING Vol.1 by Dr. B. C. Punmia]Problem 2(a) How may a chain be standardised? How may the adjustments be applied if the chain is found to be too long?
Problem 2(b) . A field was surveyed with a chain and the area was found to be 127.34 acres. If the chain used in the measurement was 0.8 percent too long, what is the correct area of the field.
Problem 7. The length of a line measured with a chain having 100 links was found to be 2000 links. If the chain was 0.5 link too short, find the true length of the line.
Problem 8. The True length of a line is known to be 500 m. The line was again measured with a 20 m tape and was found to be 502 m. What is the correct length of the 20 m tape?
Problem 9. The distance Between two Stations was measured with a 20 m chain, and found to be 1500 m. The same was measured with a 30 m chain and found to be 1476 m. If the 20 m chain was 5 cm too short, what was the error in 30 m chain.
Problem 10. A 30 m chain was tested before the commencement of the day’s work, and found to be correct. After chaining 100 chains, the chain was found to be half decimetre too long. At the end of day’s work, after chaining a total distance of 180 chains, chain was found to be one decimetre too long. What was the true distance chained.
