Variables Used
Diameter of Shaft under Flywheel - (Measured in Meter) - Diameter of Shaft under Flywheel is the diameter, of the part of the crankshaft under the flywheel, the distance across the shaft that passes through the center of the shaft is 2R (twice the radius).
Bending Moment at Crankshaft Under Flywheel - (Measured in Newton Meter) - Bending Moment at Crankshaft Under Flywheel is the bending moment at the central plane of the crankshaft when an external force or moment is applied to the crankshaft causing it to bend.
Bending Stress in Shaft Under Flywheel - (Measured in Pascal) - Bending Stress in Shaft Under Flywheel is the bending stress (tends to bend the shaft) in the part of the crankshaft under the flywheel.
STEP 1: Convert Input(s) to Base Unit
Bending Moment at Crankshaft Under Flywheel: 50000 Newton Millimeter --> 50 Newton Meter (Check conversion here)
Bending Stress in Shaft Under Flywheel: 32 Newton per Square Millimeter --> 32000000 Pascal (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
ds = ((32*Mb)/(pi*σbf))^(1/3) --> ((32*50)/(pi*32000000))^(1/3)
Evaluating ... ...

Requirements of a Piston Pin

1. The pin must have sufficient strength and flexibility to withstand the load without damage. 2. It requires high surface hardness to achieve favorable wear behavior.
3. These pins must achieve high surface quality and size accuracy for optimum fit with their sliding parts, piston, and connecting rod.
4. To keep the inertia forces to a minimum, these pins must have a low weight.
5. The rigidity of the pin should match the design of the piston, so as to avoid overloading the piston.
6. Despite from above, the pin construction should be as simple and thus economical as possible.
