Length of Bush on Crank Pin: 75.8 Millimeter --> 0.0758 Meter (Check conversion here)
Bearing Pressure of CrankPin Bush: 6.80909 Newton per Square Millimeter --> 6809090 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_c = d_cp*l_c*p_bc --> 0.0558*0.0758*6809090

Evaluating ... ...

P_c = 28799.9994276

STEP 3: Convert Result to Output's Unit

28799.9994276 Newton --> No Conversion Required

FINAL ANSWER

28799.9994276 ≈ 28800 Newton <-- Force on Crank Pin Bearing

Forces on Crank Shaft

Crankshaft is subjected to;
1. Gas forces and mass action.
2. Centrifugal force of rotating parts of connecting rod mass acts on a crank pin.
3. Bending stress.
4. Shear stress produced due to torsional moment on the shaft.
5. Fracture because of repeatative bending and torsional stresses.
6. Direct compressive stress due to radial force acting on it.
7. May subject to gyroscopic effect produced because of misalignment in main bearing & vibration damper.
