Here is how the Average Stress for Parabolic Tendons equation looks like.

10.202 = 10.006 + \frac{2}{3} \cdot (10.3 - 10.006)

10.202MPa = 10.006MPa + \frac{2}{3} \cdot (10.3MPa - 10.006MPa)

10.202 = 10.006 + \frac{2}{3} \cdot (10.3 - 10.006)

Average Stress for Parabolic Tendons Solution

Follow our step by step solution on how to calculate Average Stress for Parabolic Tendons?

FIRST Step Consider the formula

f c,avg = f c1 + \frac{2}{3} \cdot (f c2 - f c1)

Next Step Substitute values of Variables

∴

f c,avg = 10.006MPa + \frac{2}{3} \cdot (10.3MPa - 10.006MPa)

Next Step Convert Units

∴

f c,avg = 1E+7Pa + \frac{2}{3} \cdot (1E+7Pa - 1E+7Pa)

Next Step Prepare to Evaluate

∴

f c,avg = 1E+7 + \frac{2}{3} \cdot (1E+7 - 1E+7)

Next Step Evaluate

∴

f c,avg = 10202000Pa

LAST Step Convert to Output's Unit

∴

f c,avg = 10.202MPa
