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