Total Downward Force on Soil when Resultant is Outside Middle Third Solution

STEP 0: Pre-Calculation Summary
Formula Used
Total Downward Force on Soil = (Earth Pressure*3*Middle Third Distance)/2
Rv = (p*3*a)/2
This formula uses 3 Variables
Variables Used
Total Downward Force on Soil - (Measured in Newton) - Total Downward Force on Soil is the net force on soil in the vertical direction.
Earth Pressure - (Measured in Pascal) - Earth Pressure is the lateral pressure exerted by the soil on a shoring system. It is dependent on the soil structure and the interaction or movement with the retaining system.
Middle Third Distance - (Measured in Meter) - Middle Third Distance is the one-third of the total length or a=L/3.
STEP 1: Convert Input(s) to Base Unit
Earth Pressure: 83.3 Pascal --> 83.3 Pascal No Conversion Required
Middle Third Distance: 4 Meter --> 4 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Rv = (p*3*a)/2 --> (83.3*3*4)/2
Evaluating ... ...
Rv = 499.8
STEP 3: Convert Result to Output's Unit
499.8 Newton --> No Conversion Required
FINAL ANSWER
499.8 Newton <-- Total Downward Force on Soil
(Calculation completed in 00.004 seconds)
