STEP 0: Pre-Calculation Summary
Formula Used
Force on Crank Pin = pi*Inner Diameter of Engine Cylinder^2*Maximum Gas Pressure Inside Cylinder/4
Pp = pi*Di^2*pmax/4
This formula uses 1 Constants, 3 Variables
Constants Used
pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288
Variables Used
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.
Inner Diameter of Engine Cylinder - (Measured in Meter) - Inner Diameter of Engine Cylinder is the diameter of the interior or the inside surface of an engine cylinder.
Maximum Gas Pressure Inside Cylinder - (Measured in Pascal) - Maximum gas pressure inside cylinder is the maximum amount of pressure that can be generated inside the cylinder.
STEP 1: Convert Input(s) to Base Unit
Inner Diameter of Engine Cylinder: 35.69 Millimeter --> 0.03569 Meter (Check conversion ​here)
Maximum Gas Pressure Inside Cylinder: 2 Newton per Square Millimeter --> 2000000 Pascal (Check conversion ​here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Pp = pi*Di^2*pmax/4 --> pi*0.03569^2*2000000/4
Evaluating ... ...
Pp = 2000.84281903913
STEP 3: Convert Result to Output's Unit
2000.84281903913 Newton --> No Conversion Required
FINAL ANSWER
2000.84281903913 2000.843 Newton <-- Force on Crank Pin
(Calculation completed in 00.004 seconds)

Crank Pin for Different Engines

In a single-cylinder engine, straight engine, or flat engine, each crankpin normally serves just one cylinder. This results in a relatively simple design and it is the cheapest to produce. Most V engines have each pair of cylinders sharing a crankpin. This usually requires an offset between the cylinders in each bank, resulting in a simple connecting rod design. If a cylinder offset is not used, then the connecting rods must be articulated or forked at the big end. Forked connecting rods are mainly used in V-twin motorcycle engines, but in the past were found on a number of automobile and aero engines, such as the Rolls-Royce Merlin aero engine of the WWII era. Radial engines use a more complicated version of articulated connecting rods, where a single "master" connecting rod is attached to the single crankpin (one for each row in multi-row designs), and smaller bearings for each of the corresponding cylinders machined into the big end of the master rod.
