The common tangent AB of a compound curve makes an angle with the tangents of the compound curve of 25° 30' and 30°00" respectively. The stationing of A of 10 + 362 42. The degree of curve of the first curve is 4°30' while that of the second curve is 5°. It is required to change this compound curve with a simple curve that shall end at the same P.T while the direction of the tangents remains the same Find the stationing of the new P.C. O 10+333.05 O 10+313.05 O 10+331.05 O 10+311.05

Q: The tangent at the beginning of the curve at the P.C. is 125.70 m long and that at the P.T. is 155.6…

Instruments for Surveying

Surveying is the practice that determines the relative three-dimensional positions of many different points on the earth’s surface. There are various instruments used in Surveying like Theodolites, Total station, Tripod stands, Plane table, etc. for measuring horizontal angle, vertical and sloping angle, which are very useful for giving accurate and precise measurement.
