Unbraced Member Length given Critical Bending Moment of Rectangular Beam Solution

Follow our step by step solution on how to calculate Unbraced Member Length given Critical Bending Moment of Rectangular Beam?

FIRST Step Consider the formula

Len = (\frac{π}{M Cr(Rect)}) \cdot (\sqrt{e \cdot I y \cdot G \cdot J})

Next Step Substitute values of Variables

∴

Len = (\frac{π}{741N*m}) \cdot (\sqrt{50Pa \cdot 10.001kg·m² \cdot 100.002N/m² \cdot 10.0001})

Next Step Substitute values of Constants

Len = (\frac{3.1416}{741N*m}) \cdot (\sqrt{50Pa \cdot 10.001kg·m² \cdot 100.002N/m² \cdot 10.0001})

Next Step Convert Units

∴

Len = (\frac{3.1416}{741N*m}) \cdot (\sqrt{50Pa \cdot 10.001kg·m² \cdot 100.002Pa \cdot 10.0001})

Next Step Prepare to Evaluate

∴

Len = (\frac{3.1416}{741}) \cdot (\sqrt{50 \cdot 10.001 \cdot 100.002 \cdot 10.0001})

Next Step Evaluate

∴

Len = 2.99809158115557m

LAST Step Rounding Answer

∴

Len = 2.9981m
