Here is how the Normal Stress for Principal Planes at Angle of 90 degrees equation looks like.

0.0112 = \frac{1.2E-7 + 11196}{2} - \frac{1.2E-7 - 11196}{2}

0.0112MPa = \frac{1.2E-7N/m² + 11196N/m²}{2} - \frac{1.2E-7N/m² - 11196N/m²}{2}

0.0112 = \frac{1.2E-7 + 11196}{2} - \frac{1.2E-7 - 11196}{2}

Normal Stress for Principal Planes at Angle of 90 degrees Solution

Follow our step by step solution on how to calculate Normal Stress for Principal Planes at Angle of 90 degrees?

FIRST Step Consider the formula

σ n = \frac{σ 1 + σ 2}{2} - \frac{σ 1 - σ 2}{2}

Next Step Substitute values of Variables

∴

σ n = \frac{1.2E-7N/m² + 11196N/m²}{2} - \frac{1.2E-7N/m² - 11196N/m²}{2}

Next Step Convert Units

∴

σ n = \frac{1.2E-7Pa + 11196Pa}{2} - \frac{1.2E-7Pa - 11196Pa}{2}

Next Step Prepare to Evaluate

∴

σ n = \frac{1.2E-7 + 11196}{2} - \frac{1.2E-7 - 11196}{2}

Next Step Evaluate

∴

σ n = 11196Pa

Next Step Convert to Output's Unit

∴

σ n = 0.011196MPa

LAST Step Rounding Answer

∴

σ n = 0.0112MPa
