Mean bending stress in crankpin given bending moment and crankpin diameter Solution

STEP 0: Pre-Calculation Summary

Formula Used

Bending Stress in Crankpin = (32*Bending Moment at Central Plane of Crankpin)/(pi*Diameter of Crank Pin^3)
σ_bpin = (32*M_bpin)/(pi*D_cp^3)
This formula uses 1 Constants, 3 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Variables Used

Bending Stress in Crankpin - (Measured in Pascal) - Bending Stress in Crankpin is the amount of bending stress induced in the crankpin when an external force or moment is applied to the crankpin causing it to bend.
Bending Moment at Central Plane of Crankpin - (Measured in Newton Meter) - Bending Moment at Central Plane of Crankpin is the reaction induced in the central plane of the crankpin when an external force or moment is applied to the crankpin causing it to bend.
Diameter of Crank Pin - (Measured in Meter) - Diameter of Crank Pin is the diameter of the crank pin used in connecting the connecting rod with the crank.

STEP 1: Convert Input(s) to Base Unit

Bending Moment at Central Plane of Crankpin: 100000 Newton Millimeter --> 100 Newton Meter (Check conversion here)
Diameter of Crank Pin: 48 Millimeter --> 0.048 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

σ_bpin = (32*M_bpin)/(pi*D_cp^3) --> (32*100)/(pi*0.048^3)

Evaluating ... ...

σ_bpin = 9210355.5030032

STEP 3: Convert Result to Output's Unit

9210355.5030032 Pascal -->9.2103555030032 Newton per Square Millimeter (Check conversion here)

FINAL ANSWER

9.2103555030032 ≈ 9.210356 Newton per Square Millimeter <-- Bending Stress in Crankpin
