Deflection angle traverse This method of running traverses is widely employed than the other especially on open traverses. The deflection distance of a member under a load can be calculated by integrating the function that mathematically describes the slope of the deflected shape of the member under that load. In its simple form, it depends on the smallness of the angles of deflection. For example,. Since deflection angles are the basis for this method, it is recommended that points on the curve be set at 100-ft, 50-ft, or 25-ft intervals. The value of k is in terms of MPa/m (pounds per square inch per inch of deflection, or pounds per cubic inch – pci) and ranges from about 13. equally among the deflection angles. Slope of a beam : slope at any section in a deflected beam is defined as the angle in radians which the tangent at the section makes with the original axis of the beam. difference between the included angle and 180? [B]. In this paper, we give the appearances and forming mechanism of these artifacts and propose the reconstruction algorithm including a deflection angle of linear detectors. If the difference is less than 180o the included angle would be interior angle and if it is more that 180o it will be the exterior angle between the two lines forming the traverse. Preliminary survey (data gathering ) : is the gathering of data (distances, position and angles) to locate physical features (rivers, roads, structures) so that data can be plotted to scale (map or plan), also include difference in elevation so that contour could be plotted. INTERSECTING ANGLE (I) The intersecting angle is the deflection angle at the PI. 70% of that calculated from Karlsson's method.
