Vertical bending moment at central plane of side crankshaft below flywheel at max torque Solution

Follow our step by step solution on how to calculate Vertical bending moment at central plane of side crankshaft below flywheel at max torque?

FIRST Step Consider the formula
Mbv=(Pr(b+c1))-(c1(R1v+R'1v))
Next Step Substitute values of Variables
Mbv=(3118.1N(300mm+205mm))-(205mm(5100N+2300N))
Next Step Convert Units
Mbv=(3118.1N(0.3m+0.205m))-(0.205m(5100N+2300N))
Next Step Prepare to Evaluate
Mbv=(3118.1(0.3+0.205))-(0.205(5100+2300))
Next Step Evaluate
Mbv=57.6405N*m
LAST Step Convert to Output's Unit
Mbv=57640.5N*mm
