Arrange the following description in the form of profile level notes complete to elevation. A levei Is set up and a reading cf 2.995 m 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 2.625 m, 30 m from the beginring, it is 1.617 m, at 60 m, it is €.702 m, at 66 m and 81 m, the rod readings are 1.281 m and O.762 ni, 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 reck. The readings along the profile are then resumed: 90 m from the beginning of the line, 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 elevaticon at the point 60 m from the beginning of the line. b) Compute the elevation of the turning point. c) Compute the differer ce in elevation at a point 150 m and 81 m from the beginning of the line.

Transcribed Image Text:Arrange the following, description in the form of profile level notes complete to elevation. A levei
is set up and a reading 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 bégining, it is
1.617 m, at 60 m, it is €.702 m, at 66 m and 81 m, the rod readings are 1.281 m and 0.762 ni,
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 line, 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 differer ce in elevation at a point 150 m and 81 m from the beginning of the line.
