10-58.You must set a marker at a certainpoint from traverse stations3 + 00 and 4 + 25.The angle fromthe traverse line to station3 + 00 and the distance betweenthe point and station 4 + 25 aregiven.How should you proceed toset the point?1.Solve for the other angle fromthe base line, and thedistance of the point from theother station; then, set thepoint by using transit andtape.Check the distance andother angle from base line2.Solve for the angle from thebase line to the distance lineand set the point by the useof transit and tape and checkby measuring the base line3.Lay out the lines to the pointwith tape and straddlers andcheck with a transit4.Lay out the lines to the pointwith tape and straddlers andcheck by remeasuring one legof the triangle10-59.When tying in a point to a stationon a traverse, which of thefollowing conditions should youcarefully consider?1.The selected tie stationshould not be easily disturbed2.The tie station must bevisible from the point to betied in3.Both 1 and 2 above4.The angle between the tielines should be no greaterthan 90°10-60.A closed traverse was to be 15,000feet in length.The last coursewas to be 3,000 feet in length.After you turn the last deflectionangle and progress 3,000 feet onthe last course, you find that youare 3 feet from the starting pointof the traverse.What is theorder of precision?1.First2.Second3.Third4.Fourth10-61.If precision of 1/20,000 isrequired, what is the maximumallowable error of closure for atraverse of 10,560 feet?1.0.437 ft2.0.528 ft3.0.759 ft4.1.255 ftIN ANSWERING QUESTION 10-62, REFER TOTABLE 13-1 IN YOUR TEXTBOOK.10-62.1.10-63.10-64.10-65.10-66.You are running a traverse of nineinterior angles, and third-orderdegree of precision is required.Which of the following sums of theinterior angles is acceptable?1259°59’30”2.1259°59’48”3.1260°01’ 12”4.1260°01’30”A temperature correction appliedto tape measurements is consideredto be a typical precisionspecification for which of thefollowing surveys?1.Preliminary surveys2.Land surveys where the valueof the land is high3.Highway location surveys4.Both 2 and 3 aboveWhich of the following errors in atransit affects both horizontaland vertical angle measurements?1.The line of sight through thetelescope does not coincidewith the true optical axis ofthe telescope2.The horizontal axis of thetelescope is not perpendicularto the vertical axis3.The axis of each of the platelevels is not perpendicular tothe vertical axis of thetelescope4.Each of the aboveErrors that can lead to inaccuratesurveying when you use a transitmay include which of the followingnatural errors?1.Tripod settlement2.Unequal expansion of transitparts3.Refraction4.All of the aboveWhich of the following personalerrors results in a larger errorfor inclined sights than forhorizontal sights?1.Failure to focus correctly2.Failure to center the platelevel bubbles exactly3.Failure to plumb the transitexactly4.Failure to line up thevertical cross hair with thetrue vertical axis of thesighted object73
