In a two peg test using a dumpy level, the following observations were taken: Instrument at C Instrument at D Rod reading on A |1.103 568 Rod reading on B .991 .289 Point C is equidistant from A and B and D is 12m from A and 72 m from B. 0.112 What is the true difference in elevation between A and B (in meters)? (answer in 3 decimal places) With the level in the same position at D to what rod reading on B should the line of sight be adjusted (in meters)? (answer in 4 decimal places) 0.6014 What is the corresponding rod reading on A for a horizontal line of sight with instrument still at D (in meters)? (answer in 4 decimal places)
