CIVL 1112 - Assignment #10

"To be conscious that you are ignorant is a great step to knowledge." Benjamin Disraeli, British politician (1804 - 1881)

Objective

The The purpose of this assignment is threefold: (1) develop a spreadsheet that computes the balanced latitudes and departures of a traverse given the bearings and distances of each side, (2) compute the bearings of a traverse based on survey data and a reference bearing, and (3) compute your current grade in the class.

Write a spread sheet that computes corrected latitudes and departures for a traverse where angles are given by their bearings.  Compute the latitudes and departures, closure error, precision of the traverse, latitude and departure corrections, and balanced latitudes and departures.

Part 1: Compute the corrected latitudes and departures for the data show on the website. 

Part 2: Use your traverse spreadsheet to compute the corrected and balanced latitudes and departures for the traverse shown below. 

Part 3: A four-sided closed field traverse has the following distances in feet: AB = 636.45; BC = 654.49; CD = 382.85; and DA = 512.77. The interior angles are as follows: A = 81º 23'; B = 72º 33'; C = 89º 40'; and D = 116º 24'. The bearing of AB is S 33º 19' W and the side BC is in the SE quadrant. Determine the bearings of each side and then use your traverse spreadsheet to compute the corrected and balanced latitudes and departures for the traverse. Show all work for determining the bearing of each side (follow homework format)

Part 4: Use the information on the course syllabus to compute your current grade in the class.
