Resultant Outside Middle Third Solution

STEP 0: Pre-Calculation Summary

Formula Used

Middle Third Distance = 2*Total Downward Force on Soil/(3*Earth Pressure)
a = 2*R_v/(3*p)
This formula uses 3 Variables

Variables Used

Middle Third Distance - (Measured in Meter) - Middle Third Distance is the one-third of the total length or a=L/3.
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.

STEP 1: Convert Input(s) to Base Unit

Total Downward Force on Soil: 500.1 Newton --> 500.1 Newton No Conversion Required
Earth Pressure: 83.3 Pascal --> 83.3 Pascal No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

a = 2*R_v/(3*p) --> 2*500.1/(3*83.3)

Evaluating ... ...

a = 4.00240096038415

STEP 3: Convert Result to Output's Unit

4.00240096038415 Meter --> No Conversion Required

FINAL ANSWER

4.00240096038415 ≈ 4.002401 Meter <-- Middle Third Distance
