Maximum Bending Moment for Impeller Blade Solution

Follow our step by step solution on how to calculate Maximum Bending Moment for Impeller Blade?

FIRST Step Consider the formula

M m = F m \cdot (0.75 \cdot R b - R h)

Next Step Substitute values of Variables

∴

M m = 85N \cdot (0.75 \cdot 75mm - 22mm)

Next Step Convert Units

∴

M m = 85N \cdot (0.75 \cdot 0.075m - 0.022m)

Next Step Prepare to Evaluate

∴

M m = 85 \cdot (0.75 \cdot 0.075 - 0.022)

Next Step Evaluate

∴

M m = 2.91125N*m

LAST Step Convert to Output's Unit

∴

M m = 2911.25N*mm
