Bending moment at bearing 1 of side crankshaft at TDC position Solution

STEP 0: Pre-Calculation Summary

Formula Used

Bending Moment at Bearing1 of Crankshaft = Force on Crank Pin*((0.75*Length of Crank Pin)+(Thickness of Crank Web)+(0.5*Length of Bearing1 of Crankshaft))
M_b = P_p*((0.75*l_c)+(t)+(0.5*l₁))
This formula uses 5 Variables

Variables Used

Bending Moment at Bearing1 of Crankshaft - (Measured in Newton Meter) - Bending Moment at Bearing1 of Crankshaft is the moment acting on the 1st bearing of the crankshaft which tends to bend it when a force acts on it.
Force on Crank Pin - (Measured in Newton) - Force on Crank Pin is the force acting onto the crankpin used in the assembly of the crank, and the connecting rod.
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.
Length of Bearing1 of Crankshaft - (Measured in Meter) - Length of Bearing1 of Crankshaft is the length of the 1st bearing of a crankshaft and this bearing supports the crankshaft.

STEP 1: Convert Input(s) to Base Unit

Force on Crank Pin: 1950 Newton --> 1950 Newton No Conversion Required
Length of Crank Pin: 381.1111 Millimeter --> 0.3811111 Meter (Check conversion here)
Thickness of Crank Web: 40 Millimeter --> 0.04 Meter (Check conversion here)
Length of Bearing1 of Crankshaft: 15 Millimeter --> 0.015 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

M_b = P_p*((0.75*l_c)+(t)+(0.5*l₁)) --> 1950*((0.75*0.3811111)+(0.04)+(0.5*0.015))

Evaluating ... ...

M_b = 649.99998375

STEP 3: Convert Result to Output's Unit

649.99998375 Newton Meter -->649999.98375 Newton Millimeter (Check conversion here)

FINAL ANSWER

649999.98375 ≈ 650000 Newton Millimeter <-- Bending Moment at Bearing1 of Crankshaft
