STEP 1: Convert Input(s) to Base Unit

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)
Weight of Soil: 4.9 Kilonewton --> 4900 Newton (Check conversion here)
Shaft Weight in Soil Mechanics: 994.98 Kilonewton --> 994980 Newton (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_ul = pi*L*f _ut+W_soil+W_s --> pi*0.52*12+4900+994980

Evaluating ... ...

Q_ul = 999899.603538158

STEP 3: Convert Result to Output's Unit

999899.603538158 Newton -->999.899603538158 Kilonewton (Check conversion here)

FINAL ANSWER

999.899603538158 ≈ 999.8996 Kilonewton <-- Ultimate Resistance

What is Cohesionless and Cohesive Soils?

Cohesionless soil is soil that contains elements that do not stick together.
Cohesive soil means clay (fine grained soil), or soil with a high clay content, which has cohesive strength. Cohesive soil does not crumble, can be excavated with vertical sideslopes, and is plastic when moist. Cohesive soil is hard to break up when dry, and exhibits significant cohesion when submerged.

How to Calculate Ultimate Resistance for Cohesive and Cohesion less Soils?

Ultimate Resistance for Cohesive and Cohesion less Soils calculator uses Ultimate Resistance = pi*Length of Soil Section*Skin Friction Stress in Soil Mechanics+Weight of Soil+Shaft Weight in Soil Mechanics to calculate the Ultimate Resistance, The Ultimate Resistance for Cohesive and Cohesion less Soils is defined as the amount of load applied to a component beyond which the component will fail. Ultimate Resistance is denoted by Q_ul symbol.

How to calculate Ultimate Resistance for Cohesive and Cohesion less Soils using this online calculator? To use this online calculator for Ultimate Resistance for Cohesive and Cohesion less Soils, enter Length of Soil Section (L), Skin Friction Stress in Soil Mechanics (f _ut), Weight of Soil (W_soil) & Shaft Weight in Soil Mechanics (W_s) and hit the calculate button.
