is an American National Standard published by the American Society of Mechanical Engineers (ASME) that specifically focuses on the design and calculation methods for transmission shafting. While general machinery standards exist, this standard specializes in determining the necessary diameter and design factors for shafts subjected to varying torque and bending moments.

The "M" in the designation indicates that the standard included metric units, making it globally applicable for industrial machinery, automotive drivetrains, and heavy equipment. 2. The Core Engineering Formulas
Modern mechanical engineering textbooks (such as Shigley’s Mechanical Engineering Design ) teach the combination of the Von Mises stress criteria with the Modified Goodman line for fatigue. This is widely considered the industry standard for manual verification of rotating shafts. Stress Concentration Factors ( Ktcap K sub t ) from Peterson's Instead of using the generic Kmcap K sub m Ktcap K sub t Core Focus Areas: The "M" in the designation
The standard formerly known as ASME B106.1M (or ANSI/ASME B106.1M-1985), titled "Design of Transmission Shafting," is a historical engineering document that provides methods for calculating the diameter of rotating steel shafts. Status and Availability Withdrawn Status : This standard was officially withdrawn by ANSI in 1994

The ASME B16.61M standard provides essential guidelines for the design, testing, and documentation of metallic gaskets used in piping applications. This standard ensures that gaskets meet performance and safety requirements, reducing the risk of leaks and other issues in piping systems. If you're involved in piping design, procurement, or manufacturing, this standard is an essential resource.
