Thickness of crankweb given bending moment in central plane of crankweb Solution

STEP 0: Pre-Calculation Summary

Formula Used

Thickness of Crank Web = ((Bending Moment at Central Plane of Crank Web/Force on Crankweb)-(0.75*Length of Crank Pin))/0.5
t = ((M_bweb/P_web)-(0.75*l_c))/0.5
This formula uses 4 Variables

Variables Used

Thickness of Crank Web - (Measured in Meter) - Thickness of Crank Web is defined as the thickness of the crank web (the portion of a crank between the crankpin and the shaft) measured parallel to the crankpin longitudinal axis.
Bending Moment at Central Plane of Crank Web - (Measured in Newton Meter) - Bending Moment at central plane of crank web is the reaction induced in the central plane of the crank web when an external force or moment is applied to the crank web causing it to bend.
Force on Crankweb - (Measured in Newton) - Force on Crankweb is the force acting onto the crankweb used in assembly of crankshaft & connecting rod, converts reciprocation of piston to rotation of crankshaft.
Length of Crank Pin - (Measured in Meter) - Length of Crank Pin is the size of the crankpin from one end to the other and tells how long is the crankpin.

STEP 1: Convert Input(s) to Base Unit

Bending Moment at Central Plane of Crank Web: 250000 Newton Millimeter --> 250 Newton Meter (Check conversion here)
Force on Crankweb: 6500 Newton --> 6500 Newton No Conversion Required
Length of Crank Pin: 43 Millimeter --> 0.043 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t = ((M_bweb/P_web)-(0.75*l_c))/0.5 --> ((250/6500)-(0.75*0.043))/0.5

Evaluating ... ...

t = 0.0124230769230769

STEP 3: Convert Result to Output's Unit

0.0124230769230769 Meter -->12.4230769230769 Millimeter (Check conversion here)

FINAL ANSWER

12.4230769230769 ≈ 12.42308 Millimeter <-- Thickness of Crank Web
