This formula uses 4 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.
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.
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

Bending Moment at Central Plane of Crank Web: 250000 Newton Millimeter --> 250 Newton 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_bweb = (6*M_bweb)/(t^2*w) --> (6*250)/(0.04^2*0.065)

Evaluating ... ...

σ_bweb = 14423076.9230769

STEP 3: Convert Result to Output's Unit

14423076.9230769 Pascal -->14.4230769230769 Newton per Square Millimeter (Check conversion here)

FINAL ANSWER

14.4230769230769 ≈ 14.42308 Newton per Square Millimeter <-- Bending Stress in Crankweb
