21) Why is it necessary to draw a scale on the map at the time of Plotting?
22) Calculate the sag correction for a 100m tape weighting 1.3kg and used under a pull of 9 kg in equal spans of 25m each.
23) A 100m tape is held 2m out of a line. What is the true length?

Part B
1. Explain the principles of surveying? With a simple sketch state the construction and use of a cross staff
2. a. Explain the different method of ranging with neat sketch.
b. What are the accessories for a chain survey? Explain the functions of each.
3 How chain can be done on an uneven ground or sloping ground? Point out the advantages and disadvantages of this method.
4 Explain different corrections that can be applied to chain or tape.
5 Explain in details how a chain traversing can be done.
6 The distance between two points measured with a Gunter’s chain was found to be 7500 links. The same distance was measured with an Engineers chain and was found to be 4930 feet. If the Gunter’s chain was 0.25 Link too short, what was error in engineer’s chain?
7 A chain was tested before starting a survey and was found to be exactly 20m and 20cm. The area of the plan drawn to a scale 8cm to 1cm was 220sq.cm. Find the true area of the field.
8 A 30m chain was found to be 0.1m too long after chaining 2400m. If the chain was correct before commencement of the work, find the true distance.
9. A 30m steel tape was standardized on the flat and was found to be exactly 3mm under no pull at 66°F. It was used in catenar to measure a base of 5 bays the temperatureduring the measurement was 92°F and the pull exerted during the measurement was 10kg. The area of the cross section of the tape was 0.08 sq.cm and the specific weights of steel is 7.86 g/cc. A = 0.0000063 per 1°F and e = 2.109 x 10 6 kg/sq.cm. Find the true length of the line. 10 A steel exactly 30m long at 18°C when supported throughout its length under a pull of 8 kg, A line was measured with a tape under a pull of 12 kg and found to be 1602 m. the mean temperature during the measurement was 26 C. Assuming the tape to be supported at every 30m, calculate the length of the line, given that cross sectional area of the tape is 0.04 sq.cm, the weight of 1 cc = 0.0077 kg, the co efficient of expansion = .000012 per 1°C, and the modulus of elasticity = 2.1 x 10 3 kg / sq.cm
