Objective Statement: To gain an understanding of measurements and error calculations in Civil Engineering problems while using prior knowledge of geometry, spreadsheets, and trigonometry to solve such problems. Introduction: In lectures and the lab time before we began the actual work on this lab, we have been discussing error calculations such and the Mean, Standard Deviation, Variance, and Standard Error of the Mean. This lab was intended to take those discussions and bring them into some real problems that related to Civil Engineering. The 3 sections got progressively more involving until, in section 3, we did nearly all of the recording of statistics rather than having them given to us. Procedures: Section 1: 1) Find the slope of line 1 (slope equals y2-y1/x2-x1) 2) Use the slope and a point on the graph to calculate the y-intercept using the equation of a line, y=mx+b 3) Take the tangent of 30 degrees to find the slope of line 2. 4) Use point-slope form to find the equation of line 2. Point-slope form: (y-y1)=m(x-x1) where (x1,y1) is he point you are given. 5) Set the 2 equations equal to each other. mx + b(line1)=mx + b(line2) to find the x-value of the intersection point. 6) Use the resultant value in the equation for line one to find the y-value of the intersection point. Section 2:
