Bending Moment in vertical plane of side crankshaft at TDC position below flywheel due to flywheel Solution

Follow our step by step solution on how to calculate Bending Moment in vertical plane of side crankshaft at TDC position below flywheel due to flywheel?

FIRST Step Consider the formula

M v = (P cr \cdot (c 1 + b)) - (c 1 \cdot (R 1 + R' 1))

Next Step Substitute values of Variables

∴

M v = (5466.833N \cdot (205mm + 300mm)) - (205mm \cdot (11050N + 2300N))

Next Step Convert Units

∴

M v = (5466.833N \cdot (0.205m + 0.3m)) - (0.205m \cdot (11050N + 2300N))

Next Step Prepare to Evaluate

∴

M v = (5466.833 \cdot (0.205 + 0.3)) - (0.205 \cdot (11050 + 2300))

Next Step Evaluate

∴

M v = 24.000665N*m

LAST Step Convert to Output's Unit

∴

M v = 24000.665N*mm
