Problem 1. Arrange the following description in the form of profile level notes complete to elevation. A level is set up and a readir.g of 2.995 m is taken on a bench mark the elevation of which is 12.135 m. At the beginning of the line to be profiled, the rod reading is 2.625 m, 30 m from the beginning, it is 1.617 m, at 60 m, it is 0.702 m, at 66 m and 81 m, the rod readings are 1.281 m and 0.762 m, respectively. On a rock that is not on the line, the rod reading is 0.555 m. The level is then removed ahead, set up and a rod reading of 1.952 m is observed, the rod still being held on the rock. The readings along the profile are then resumed: 90 m from the beginning of the iine, the rod reading is 1.159 m, 120 m from the beginning of the line rod reading is 1.434 m, and finally 150 m from the beginning of the line the rod reading is 2.196 m. a) Compute the elevation at the point 60 m from the beginning of the line. b) Compute the elevation of the turning point. c) Compute the difference in elevation at a point 150m and 81 m from the beginning of the line.
