Bending moment in specimen given bending stress Solution

Follow our step by step solution on how to calculate Bending moment in specimen given bending stress?

FIRST Step Consider the formula

M b = \frac{σ b \cdot I}{y}

Next Step Substitute values of Variables

∴

M b = \frac{56N/mm² \cdot 44000mm⁴}{21mm}

Next Step Convert Units

∴

M b = \frac{5.6E+7Pa \cdot 4.4E-8m⁴}{0.021m}

Next Step Prepare to Evaluate

∴

M b = \frac{5.6E+7 \cdot 4.4E-8}{0.021}

Next Step Evaluate

∴

M b = 117.333333333333N*m

Next Step Convert to Output's Unit

∴

M b = 117333.333333333N*mm

LAST Step Rounding Answer

∴

M b = 117333.3333N*mm
