Fully Plastic Bending Moment Solution

Follow our step by step solution on how to calculate Fully Plastic Bending Moment?

FIRST Step Consider the formula

M f = \frac{b \cdot d^{2} \cdot σ 0}{4}

Next Step Substitute values of Variables

∴

M f = \frac{80mm \cdot {100mm}^{2} \cdot 240MPa}{4}

Next Step Convert Units

∴

M f = \frac{0.08m \cdot {0.1m}^{2} \cdot 2.4E+8Pa}{4}

Next Step Prepare to Evaluate

∴

M f = \frac{0.08 \cdot {0.1}^{2} \cdot 2.4E+8}{4}

Next Step Evaluate

∴

M f = 48000N*m

Next Step Convert to Output's Unit

∴

M f = 48000000N*mm

LAST Step Rounding Answer

∴

M f = 4.8E+7N*mm
