R_v = q*B+((γ*B^2*tan(φ)*(pi/180))/4)
This formula uses 1 Constants, 1 Functions, 5 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Functions Used

tan - The tangent of an angle is a trigonometric ratio of the length of the side opposite an angle to the length of the side adjacent to an angle in a right triangle., tan(Angle)

Variables Used

Total Downward Force in Soil - (Measured in Newton) - Total Downward Force in Soil is the net force on soil in the vertical direction.
Load Intensity - (Measured in Pascal) - Load Intensity is defined as load applied per unit area.
Width of Footing - (Measured in Meter) - Width of Footing is the shorter dimension of the footing.
Unit Weight of Soil - (Measured in Newton per Cubic Meter) - Unit Weight of Soil mass is the ratio of the total weight of soil to the total volume of soil.
Angle of Shearing Resistance - (Measured in Radian) - Angle of Shearing Resistance is known as a component of the shear strength of the soils which is basically frictional material and composed of individual particles.

STEP 1: Convert Input(s) to Base Unit

Load Intensity: 26.8 Kilopascal --> 26800 Pascal (Check conversion here)
Width of Footing: 2 Meter --> 2 Meter No Conversion Required
Unit Weight of Soil: 18 Kilonewton per Cubic Meter --> 18000 Newton per Cubic Meter (Check conversion here)
Angle of Shearing Resistance: 82.57 Degree --> 1.44111836337145 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

R_v = q*B+((γ*B^2*tan(φ)*(pi/180))/4) --> 26800*2+((18000*2^2*tan(1.44111836337145)*(pi/180))/4)

Evaluating ... ...

R_v = 56009.0159430866

STEP 3: Convert Result to Output's Unit

56009.0159430866 Newton -->56.0090159430866 Kilonewton (Check conversion here)

FINAL ANSWER

56.0090159430866 ≈ 56.00902 Kilonewton <-- Total Downward Force in Soil
