M_b = (pi*d_cp^3*σ_b)/32
This formula uses 1 Constants, 3 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Variables Used

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.
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.

STEP 1: Convert Input(s) to Base Unit

Diameter of Crank Pin: 73.47 Millimeter --> 0.07347 Meter (Check conversion here)
Bending Stress in Crankpin: 19 Newton per Square Millimeter --> 19000000 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

M_b = (pi*d_cp^3*σ_b)/32 --> (pi*0.07347^3*19000000)/32

Evaluating ... ...

M_b = 739.747685215069

STEP 3: Convert Result to Output's Unit

739.747685215069 Newton Meter --> No Conversion Required

FINAL ANSWER

739.747685215069 ≈ 739.7477 Newton Meter <-- Bending Moment at Central Plane of Crankpin

(Calculation completed in 00.008 seconds)

What is an Engine Knock?

Knocking occurs when fuel burns unevenly in your engine's cylinders. When cylinders have the correct balance of air and fuel, fuel will burn in small, regulated pockets instead of all at once. (Think sparklers, not fireworks.) After each pocket burns, it creates a little shock, igniting the next pocket and continuing the cycle. Engine knocking happens when fuel burns unevenly and those shocks go off at the wrong time. The result? An annoying noise and potential damage to your engine's cylinder walls and pistons. Faulty spark plugs, Low octane fuel, Carbon deposits cause knocking in an engine.
