Find the combined sectional inertial moment of this diagram
Thread Content
Please, experts, include the calculation formulas as well. Thank you!
There is a book titled Quick Reference Manual for the Design of Petrochemical Equipment; Chapter 8, section 1.13, covers the calculation of the inertial moment of stiffening rings along with examples. Take a look at the example; it’s easy to calculate.
Could you upload the electronic version? :lol
Your book probably refers to the calculation of the effective inertial moment of the reinforcement ring, while mine deals with the calculation of the effective inertial moment for a combination of a reinforcement ring, a cylindrical reinforcement section, and a conical shell reinforcement section.
Have you seen the content in the book? The method is the same.

I’ve seen it; it doesn’t cover such methods.
Draw it in AutoCAD and combine it into a solid. By querying the domain properties, one can find the centroid of the domain. By moving the centroid to the 0 point and then querying the domain properties again, the moment of inertia is what you need.
