Where R is the major radius (distance from center to tube center), r is the minor radius (tube radius)
📖 About Torus
A torus (also called a ring or tire shape) is a geometric shape formed by rotating a circle around an axis in its plane that does not intersect it. The shape resembles a tire or donut.
Torus Features:
- Has a central hole
- Cross-section is circular
- No edges or vertices
- Is a surface of revolution
Applications:
- Tires, inner tubes
- Donuts, bagels
- Life buoys
- Some pipe fittings
