Next Step Prepare to Evaluate
Lc=(43)(1003100)
Next Step Evaluate
Lc=0.043010752688172m
Next Step Convert to Output's Unit
Lc=43.010752688172mm
LAST Step Rounding Answer
Lc=43.0108mm

Length of crankpin given mean bending moment in crankpin Formula Elements

Variables
Length of Crank Pin
Length of Crank Pin is the size of the crankpin from one end to the other and tells how long is the crankpin.
Symbol: Lc
Measurement: LengthUnit: mm
