Prestressing Force at distance x when Reverse Friction is Considered Solution

Follow our step by step solution on how to calculate Prestressing Force at distance x when Reverse Friction is Considered?

FIRST Step Consider the formula

P x = (P - Δf p) \cdot \exp (η \cdot x)

Next Step Substitute values of Variables

∴

P x = (20.01kN - 10MPa) \cdot \exp (6 \cdot 10.1mm)

Next Step Convert Units

∴

P x = (20010N - 10MPa) \cdot \exp (6 \cdot 0.0101m)

Next Step Prepare to Evaluate

∴

P x = (20010 - 10) \cdot \exp (6 \cdot 0.0101)

Next Step Evaluate

∴

P x = 21249.4767928419N

Next Step Convert to Output's Unit

∴

P x = 21.2494767928419kN

LAST Step Rounding Answer

∴

P x = 21.2495kN
