Bending stress in central plane of crankweb Solution

STEP 0: Pre-Calculation Summary

Formula Used

Bending Stress in Crankweb = (6*(Force on Crankweb*(Length of Crank Pin*0.75+Thickness of Crank Web/2)))/(Thickness of Crank Web^2*Width of Crank Web)
σ_b = (6*(P*(l_c*0.75+t/2)))/(t^2*w)
This formula uses 5 Variables

Variables Used

Bending Stress in Crankweb - (Measured in Pascal) - Bending Stress in Crankweb is the bending stress in the crank web due to the bending moment acting onto the crank web.
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.
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.
Width of Crank Web - (Measured in Meter) - Width of Crank Web is defined as the width of the crank web (the portion of a crank between the crankpin and the shaft) measured perpendicular to the crankpin longitudinal axis.

STEP 1: Convert Input(s) to Base Unit

Force on Crankweb: 6500 Newton --> 6500 Newton No Conversion Required
Length of Crank Pin: 24.6 Millimeter --> 0.0246 Meter (Check conversion here)
Thickness of Crank Web: 40 Millimeter --> 0.04 Meter (Check conversion here)
Width of Crank Web: 65 Millimeter --> 0.065 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

σ_b = (6*(P*(l_c*0.75+t/2)))/(t^2*w) --> (6*(6500*(0.0246*0.75+0.04/2)))/(0.04^2*0.065)

Evaluating ... ...

σ_b = 14418750

STEP 3: Convert Result to Output's Unit

14418750 Pascal -->14.41875 Newton per Square Millimeter (Check conversion here)

FINAL ANSWER

14.41875 Newton per Square Millimeter <-- Bending Stress in Crankweb
