Calculate nominal maximum bending stress in a solid circular shaft.

PRELIMINARY RESULT

Maximum bending stress162.97 MPa

Formula: σmax = 32M / (πd³)

The elastic flexure formula is applied to a solid circular shaft.

FORMULA VERIFICATION

Reference: Shigley, Mechanical Engineering Design, circular-shaft torsion and elementary beam theory.

Internal unit basis: N, mm, MPa and SI rotational units converted explicitly. Outputs: tool-specific SI engineering units.

Valid conditions: Positive finite geometry, load and source-controlled property inputs.

Limitations: Preliminary elastic screening only; no code-compliance, detailed stress concentration or service spectrum design.
