1. Length of a line measured with an Engineer’s chain (100 ft) was found to be
820 ft. it was afterwards found that the chain was 3 inches long. Find the true
length of the line?
2. Length of a line measured with an Engineer’s chain (100 ft) was found to be
820 ft. It was found that the error in chain at start was 3 inches long & 9 inches
long at the end. Find the true length of the line?
3. Stations are measured by means of a Gunter’s chain (66 ft) which was 0.4 links
too short and the result was 1248 links. What was the true distance between
the stations in feet? Hint: Length of each link is 0.66 ft.
4. A 100-ft steel tape known to be only 99.98 ft long under standard conditions
was used to record a measurement of 398.36 ft. What is the distance corrected
for erroneous tape length?
5. Length of line measured by means of a 100 ft chain was found to be 2240 ft
and the true length of the line was 2245 ft. what was the actual measured length
of the chain?
6. An Engineer’s chain was found to be 7.5 cm too long after chaining 120 m. It
was found to be 15 m too long at the end of the day’s work, after chaining a
total distance of 210 m. If the chain was correct before the commencement of
work, find the true distance.
7. The distance between two points A and B measured along the slope was 1980
m. Determine the horizontal distance between A and B if (a) the angle of slope
is 8 degree (b)the slope is 1 in 5 (c) the difference of level of A and B is 80 m.
8. The area of the field as calculated from measurements taken with a 20 m chain
0.5 link too short, is found to be 120 hectares. What is the true area of the field?
9. Convert the following whole circle bearings to reduced/quadrant bearings.
43° 00’36”, 141°25’34”, 230°12’20”, and 330°35’48”
98°12’55”, 153°26’40”, 192° 56’22”, and 288°12’50”
10. Convert the following reduced/ quadrant bearings to whole circle bearings.
N44°50’38”E, S38°42’54”E, S45°06’02”W, and N13°24’30”W
N32°42’38”E, S54°02’02”E, S22°42’56”W, and N44°35’26”W
