You have your work cut out for you.In summary, the person is looking for the method to manually calculate the mass moment of inertia for an assembly consisting of an angle L bent in the form of a parabola and attached to a H section bent in the form of a circle. They have a diagram of the assembly and are currently using Solid Edge as a CAD program. The expert suggests using a CAD program to do the calculations, but the person wants to do it mathematically. The expert advises that the calculation would require a long process using calculus and recommends using Autodesk Inventor, a free student edition of a CAD program. The person is doing a project and wants to do the calculations themselves.

In any event, calculating the MMOI could conceivably be done manually by means of a mass take-off, but it would be a pretty tedious process.

Can you tell me the basic method to calculate manually MMOI?

This was why I mentioned using a CAD program to do the calculations. It's a lot quicker and much less prone to error. IDK if you are using any particular CAD programs in your ME studies, but a package like Autodesk Inventor should have the tools necessary to do MMOI calculations for this structure.

Even if you don't have access to Autodesk Inventor as part of your studies, you can download a free student edition:

Good Luck!

The moment of inertia of a "L" angle bent in a parabola is a measure of its resistance to changes in rotational motion. It is a mathematical property that depends on the shape, size, and distribution of mass in an object.

The moment of inertia of a "L" angle bent in a parabola can be calculated by using the equation: I = (1/12) * m * (h^2 + 3b^2), where m is the mass of the object, h is the height of the parabola, and b is the base length of the angle.

The moment of inertia of a "L" angle bent in a parabola is important in engineering and physics as it helps in understanding and predicting the behavior of objects under rotational motion. It also plays a crucial role in designing structures and machines that require stable and efficient movement.

Yes, there are other methods for calculating the moment of inertia of a "L" angle bent in a parabola, such as the parallel axis theorem and the perpendicular axis theorem. These methods can be used to calculate the moment of inertia for more complex shapes and distributions of mass.

The moment of inertia of a "L" angle bent in a parabola directly affects its rotational motion. Objects with a higher moment of inertia require more torque to rotate and have a slower rate of rotational motion. Objects with a lower moment of inertia require less torque and have a faster rate of rotational motion.
