Question

shoot an azimuth, hold the compass about waist level so that the direction arrow points dire azimuth aligned with the direction the needle can swing freely y away from you. Rotate the compass housing so that the needle aligns wi or O on the compass housing). The degree mark on the housing that is arrow is your azimuth. Be sure to hold the compass level so that wo azimuth readings are usually taken to insure the accuracy. After sighting trom A to point B, read an azimuth in the opposite direction, from point B to point A. It the measurements are accurate, there will be a 180 degree difference. int Measure 3 azimuths based on sites given by the lab instructor. Positions Azimuth Back Difference in Degrees Azimuth Aand B K2 1722 Cand D 43 20 and F G and H 46332 Pacing Pacing will be one of the methods you use to measure distance. There are more accurate methods. However, it is important to able to draw rough maps when instruments are not available. Pacing can be moderately accurate except on rough terrain,. The lab instructor has marked a distance of ft or m. Walk from one end to the other counting your paces, or steps. Walk this distance 3 times to determine your average pace. Number Distance Average of Paces per Pace Pace ftor m Triangulation Triangulation is a method of locating a point by taking at least two azimuths from known locations, and can be used to determine the distance to a site without direct measurement. To locate an object, measure the azimuth to the object from both ends of a baseline with a known length. The position of the object is determined by the intersection of two azimuths, as shown in Figure 1.2.

Explanation / Answer

The difference should b 180 degree hence

Positions Azimuth Back Azimuth Difference in degrees

A-B 182 2 180

C-D 48 228 180

E-F 214 34 180

G-H 146 326 180

Pacing( I'm not sure about it)

Consider,

One pace = 1m

Now if we consider the number of paces as a distance from one end to another then

1) In first case it is 40. 5, it I consider this as a distance then according to the condition that distance should be 3 times of the total distance then it becomes 40. 5 x 3 = 121. 5

Now distance per pace will be 121. 5/ 40. 5 = 3m

The average pace = total no of pace / total distance = 40. 5/121. 5= 0. 33

2) Now for 39. 25, it becomes 39. 25 x 3 =117. 75

Now distance per pace will be 117.75 / 39.25 = 3m

The average pace = total no of pace / total distance = 39. 25/117. 75 = 0. 33

3) now for 40, it becomes 40 x 3 = 120

now distance per pace will be 120/40 = 3m

The average pace = total no of pace / total distance = 40 /120 = 0. 33

Total average pace = 0. 33+.0.33 + 0. 33 = ~1m
