Allowable Unit Stress on Timber Columns of Square or Rectangular Cross Section Solution

Follow our step by step solution on how to calculate Allowable Unit Stress on Timber Columns of Square or Rectangular Cross Section?

FIRST Step Consider the formula

P|A = \frac{0.3 \cdot E}{{(\frac{L}{d})}^{2}}

Next Step Substitute values of Variables

∴

P|A = \frac{0.3 \cdot 50MPa}{{(\frac{1500mm}{200mm})}^{2}}

Next Step Convert Units

∴

P|A = \frac{0.3 \cdot 5E+7Pa}{{(\frac{1.5m}{0.2m})}^{2}}

Next Step Prepare to Evaluate

∴

P|A = \frac{0.3 \cdot 5E+7}{{(\frac{1.5}{0.2})}^{2}}

Next Step Evaluate

∴

P|A = 266666.666666667Pa

Next Step Convert to Output's Unit

∴

P|A = 0.266666666666667MPa

LAST Step Rounding Answer

∴

P|A = 0.2667MPa
