Weight of Shaft given Ultimate Resistance Solution

STEP 0: Pre-Calculation Summary

Formula Used

Shaft Weight = (Ultimate Resistance-Weight of Soil)/(pi*Length of Soil Section*Skin Friction Stress in Soil Mechanics)
W_p = (Q_ul-W_soil)/(pi*L*f _ut)
This formula uses 1 Constants, 5 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Variables Used

Shaft Weight - (Measured in Newton) - Shaft Weight is the weight of the pile shaft.
Ultimate Resistance - (Measured in Newton) - Ultimate Resistance is the amount of load applied to a component beyond which the component will fail.
Weight of Soil - (Measured in Newton) - Weight of Soil is the weight of soil contained within the failure plane.
Length of Soil Section - (Measured in Meter) - Length of Soil Section is the vertical or horizontal extent of soil being analyzed or considered within a specific context.
Skin Friction Stress in Soil Mechanics - (Measured in Pascal) - Skin Friction Stress in Soil Mechanics is the average ultimate skin- friction stress in tension developed on the failure plane.

STEP 1: Convert Input(s) to Base Unit

Ultimate Resistance: 1000 Kilonewton --> 1000000 Newton (Check conversion here)
Weight of Soil: 4.9 Kilonewton --> 4900 Newton (Check conversion here)
Length of Soil Section: 0.52 Meter --> 0.52 Meter No Conversion Required
Skin Friction Stress in Soil Mechanics: 0.012 Kilonewton per Square Meter --> 12 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

W_p = (Q_ul-W_soil)/(pi*L*f _ut) --> (1000000-4900)/(pi*0.52*12)

Evaluating ... ...

W_p = 50761.244830367

STEP 3: Convert Result to Output's Unit

50761.244830367 Newton -->50.761244830367 Kilonewton (Check conversion here)

FINAL ANSWER

50.761244830367 ≈ 50.76124 Kilonewton <-- Shaft Weight
