The slope and y-intercept calculator takes a linear equation and allows you to calculate the slope and y-intercept for the equation. 12-15) for the slope correction is as follows: But for a small slope, d is approximately equal to s; therefore, Correction for Slope Civil Engineering Thus the correction is ve. Have a good day. The sign of the correction (Ca) will be the same as that of c. it may be noted that L and l must be expressed in the same units and the unit of Ca is the same as that of c. Correction for Temperature: - It is necessary to apply this correction, since the length of a tape is increased as its temperature is raised, and consequently, the measured distance is too small. L = [D + h] 265 = [D + Eight] D = [265 Eight] D = 70,161. S s bisht said: 8 months ago (1) Jahangir Abbas Sahil said: 1 year ago V. Deepa said: 2 years ago It is given by the formula, Cs = l1 (mgl1)2 / 24P2 = l1(Mg)2 / 24P2 (4). When you plot those two data pairs as points and draw a line between them (the calibration curve), then assuming the response of the thermometer is linear, you could pick any point on the line that corresponds to the value the thermometer displays, and you could find the corresponding true temperature. Hence, This is defined as the ratio between the maximum height of a slope to the actual height of a slope and may be expressed as follows: FH = Hmax H (11.5) The factors of safety F c, F , F H are only occasionally used in slope stability analyses.

Slope is basically the change in the y direction divided by the change in the x direction. Using the second equation: Hold the tape level (if the elevation differential is not too great and if you have a device for assuring the tape is level), Measure the actual (slope) distance, measure the slope between stations, and correct for slope after making the measurements. Tape Corrections: - Precise measurements of distance is made by means of a steel tape 30 m or 50 m in length. If l is the length of any one slope, and h the difference in height between the ends of the slope, = l l (1 h2 / 2l2 h4 / 3l4 etc..), =(h2 / 2l + h4 / 3l3 + etc.) Tape Corrections Using the approximate slope correction formula for gentle slopes, determine the horizontal length of line ABC.

To find the bias, call the second element of vector x. bias = x (2) bias = 999.500007629511. The case of a randomly Correlation Formula The horizontal distance between two points D = [ Measured distance - slope correction] = [ 265m - 0.1207m.] Before use it is desirable to ascertain its actual length (absolute length) by comparing it with the standard of known length, which can be done for a small fee by the Survey and Standards department. The horizontal distance between two points D = [ Measured distance - slope correction] = [ 265m - 0.1207m.] Correction for Absolute Length: - It is the usual practice to express the absolute length of a tape as its nominal or designated length plus or minus a correction. To our sheet (in row 14) weve added titles for those three functions. b = y - m x = 1 - 21 = -1. This article is a guide to Correlation Formula.
