2. Q1) Answer the following statements (T) or ( F) : a- A sag error can be eliminated by decreasing the applied tension. b- A steel tape measurement was entered in the field book as being m. because the temperature at the time of measurement was 550 F, resulting in the tape shrinking to only m m must be added to the recorded distance to have the corrected value. c- A percent slope is one that rises m in m. d- The slope distance between two points is m and the slope angle is 1042/. The horizontal distance is m.

3. Q2) Station 2+04. 67 must be marked in the field
Q2) Station must be marked in the field. If the steel tape to be used is only m (under standard condition). How far from the existing station mark at

4. Q3) You must establish the elevation of point B from point A (elevation m). Points A and B are on opposite sides of a 12 – lane highway. With th following results: Set-up at A side of highway Rod reading at A = m Rod reading at B = m Set-up at B side of highway Rod reading at B = m Rod reading at A = m a) What is the elevation of point B? b) What is the leveling error?

5. Q4) A highway baseline was run down a very steep hill as shown in Figure below. Rather than measure horizontally downhill with the steel tape, the surveyor measures the vertical angle with the a theodolite and the slope distance with a 200 m steel tape. The vertical angle is -21o26/ turned to a point on a plumbed range pole that is 4.88 m above the ground. The slope distance from the theodolite to the point on the range pole is m. the theodolites optical center is 4.66 m above the upper baseline station at The elevation of the upper station is , compute the following: (a) The elevation of the lower station (b) The chainage lower station
