1 CVEN303 Engineering Measurement Fall 2009 Homework Assignment # 4 KEY Due : One week from the day the HW was posted (Due to 10/28/2009 for Sections 501, 502, and 503). Leveling Errors Due to Curvature and Refraction ( Read sections 2.2 and 2.3 in the book ) 1. (5+5 points) Compute the error due to curvature and refraction for the following distances: 350 ft and 115 m (c+r) = 0.0206 * (350/1000) 2 = 0.0025 ft (c+r) = 0.0675 * (115/1000) 2 = 0.0009 m Profile Leveling ( Read section 2.9 in the book ) 2. (20 points) Work problem 2.5 (measurements are in ft) 3. (10 +10 points) Work problems 2.8 and 2.9
