B Can only one help me build prototype or simulation

AI Thread Summary
The discussion centers on a system involving a hollow cylinder and a rotating sphere, raising questions about the energy required for rotation and the energy acquired by the sphere. Participants express skepticism about the feasibility of the setup, suggesting it resembles a perpetual motion machine, which is prohibited in the forum. The critical angle of tilt is defined as the maximum angle before tipping occurs, crucial for stability analysis. Concerns are raised about the source of energy for the system and the specifics of the components' centers of mass. The thread is ultimately closed for moderation due to its potential alignment with pseudoscientific concepts.

TL;DR Summary
Asking for help with simulation before building a prototype
A hollow cylinder with dimensions 2 m radius,6 m height and weight 200kgs

And a massive sphere weight 2000kgs with radius 30cm is placed inside the cylinder and is free to rotate.

Now the whole system is tilted to it's critical angle and is rotated around a circular track. The circumference of cylinder base and circular track is same .

Calculate the energy required to rotate the system at 5 radius/sec and also calculate the energy acquired by the sphere inside the cylinder

This sounds suspiciously like a perpetual motion device. PMMs are a forbidden subject here. This thread is almost certainly going to be locked, but let's be sure.

What is the source of the energy in your system?

(And where will you get this 2 foot sphere of Platinum?)

What exactly do you mean by "critical angle"? And what are the distances from the center to the centers of mass of the system, the cylinder, and the sphere?

This will require knowing how the centers of mass of the various components are moving, which is why I'm asking

The sphere is made of iron and not platinum.
The source of energy is external. I want to calculate the energy required to rotate the system vs the energy acquired by the sphere which is rotating inside the cylinder

The critical angle of tilt is the maximum angle at which an object can be tilted before it begins to tip over. This angle is crucial for understanding the stability of the object. It’s determined by the balance of forces acting on the object, especially the gravitational force and the supporting base.

For example, if you tilt a cylinder, the critical angle is where the center of mass aligns with the edge of the base, just before it would cause the cylinder to fall. This angle depends on the height of the object's center of mass and the width of its base.

tan⁡(θc)=hCoMb/2
Where hCoM is the height of the center of mass and b is the width of the base.

The concept is widely used in engineering and physics to design stable structures and systems, ensuring they don’t tip over easily

Thread will remain closed for now, since it appears that this may be a PMM discussion attempt, which is against the PF rules:
