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

D_s = ((32*M_b)/(pi*σ_b))^(1/3) --> ((32*50)/(pi*32000000))^(1/3)

Evaluating ... ...

D_s = 0.0251539799580218

STEP 3: Convert Result to Output's Unit

0.0251539799580218 Meter -->25.1539799580218 Millimeter (Check conversion here)

FINAL ANSWER

25.1539799580218 ≈ 25.15398 Millimeter <-- Diameter of Shaft Under Flywheel

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.
