Flow Stress Solution

Follow our step by step solution on how to calculate Flow Stress?

FIRST Step Consider the formula

FS = {ϵ T}^{SHC} \cdot SC

Next Step Substitute values of Variables

∴

FS = {0.01}^{2.2} \cdot 5

Next Step Prepare to Evaluate

∴

FS = {0.01}^{2.2} \cdot 5

Next Step Evaluate

∴

FS = 0.000199053585276748

LAST Step Rounding Answer

∴

FS = 0.0002
