Weighted Friction Angle given Mobilised Friction Angle Solution

STEP 0: Pre-Calculation Summary
Formula Used
Weighted Friction Angle = (Submerged Unit Weight*Angle of Mobilized Friction)/Saturated Unit Weight
φw = (γ'*φm)/γsat
This formula uses 4 Variables
Variables Used
Weighted Friction Angle - (Measured in Radian) - Weighted Friction Angle is an effective measure combining materials' friction properties and their relative contributions in geotechnical engineering for stability analysis.
Submerged Unit Weight - (Measured in Newton per Cubic Meter) - Submerged Unit Weight is the effective weight of the soil per unit volume when it is submerged in water.
Angle of Mobilized Friction - (Measured in Radian) - Angle of Mobilized Friction is the slope angle at which an object starts sliding due to applied force.
Saturated Unit Weight - (Measured in Newton per Cubic Meter) - Saturated Unit Weight is the value of the unit weight of the soil when the soil is completely saturated with water that is all the soil pores are completely filled with water.
STEP 1: Convert Input(s) to Base Unit
Submerged Unit Weight: 31 Newton per Cubic Meter --> 31 Newton per Cubic Meter No Conversion Required
Angle of Mobilized Friction: 40 Degree --> 0.698131700797601 Radian (Check conversion ​here)
Saturated Unit Weight: 9.98 Newton per Cubic Meter --> 9.98 Newton per Cubic Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
φw = (γ'm)/γsat --> (31*0.698131700797601)/9.98
Evaluating ... ...
φw = 2.16854536319896
STEP 3: Convert Result to Output's Unit
2.16854536319896 Radian -->124.248496993988 Degree (Check conversion ​here)
FINAL ANSWER
124.248496993988 124.2485 Degree <-- Weighted Friction Angle
