Question
Problems electrical cable is on the crosshair of the leveled clinometer. At this point, surveyors A and B determine the distance between them to be 17.4 ft (see figure). Surveyor A then sets the clinometer to 0° and sights surveyor B; this horizontal line of sight cuts surveyor B at the knees, a distance of 2.0 ft above the ground. Determine the ground clearance of the electrical cable. 3.1 A Gunter's chain was used to take the follow- ing measurements. Convert these distances to feet and meters. a. 65 chains, 15 links; b. 105 chains, 11 links; c. 129.33 chains; d. 7 chains, 41 links. 3.7 A 100-ft steel tape known to be only 99.98 ft long (under standard conditions) was used to record a measurement of 276.22 ft. What is the distance corrected for the erroneous tape? 3.8 A 30-m steel tape, known to be 30.004 m (under standard conditions), was used to 3.2 A 100-ft "cut" steel tape was used to mea- sure between two property markers. The rear surveyor held 52 ft, while the head surveyor cut 0.27 ft. What is the distance between the markers? 3.3 The slope measurement between two points is 36.255 m and the slope angle is 1"50'.

Compute the horizontal distance. should be laid out? 3.10 A survey distance of 287.13 ft was recorded when the field temperature was 96°F. What is the distance, corrected for temperature? 3.6 The ground clearance of an overhead electri- cal cable must be determined. Surveyor B is positioned directly under the cable (surveyor 3.11 Station 2 + 33.33 must be marked in the B can make a position check by sighting past the string of a plumb bob, held in his or her outstretched hand, to the cable); surveyor A sets the clinometer to 45° and then backs away from surveyor B until the overhead field.
