1. What is Midsphere Radius of Triakis Octahedron?

The Midsphere Radius of Triakis Octahedron is the radius of the sphere for which all the edges of the Triakis Octahedron become a tangent line on that sphere. It's an important geometric property in polyhedral studies.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ r_m = \frac{1}{2} \times \frac{r_i}{\sqrt{\frac{5 + 2\sqrt{2}}{34}}} \]

Where:

Explanation: This formula establishes the mathematical relationship between the midsphere radius and insphere radius of a Triakis Octahedron, incorporating the geometric constant \( \sqrt{2} \).

3. Importance of Midsphere Radius Calculation

Details: Calculating the midsphere radius is crucial for understanding the geometric properties of Triakis Octahedron, including its symmetry, packing efficiency, and spatial relationships in three-dimensional space.

4. Using the Calculator

Tips: Enter the insphere radius value in meters. The value must be a positive number greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a Triakis Octahedron?
A: A Triakis Octahedron is a Catalan solid that is the dual of the truncated cube. It has 24 isosceles triangular faces.

Q2: How is midsphere radius different from insphere radius?
A: The insphere radius touches all faces of the polyhedron, while the midsphere radius is tangent to all edges of the polyhedron.

Q3: What are the practical applications of this calculation?
A: This calculation is used in crystallography, material science, and architectural design where geometric properties of polyhedra are important.

Q4: Can this formula be used for other polyhedra?
A: No, this specific formula applies only to Triakis Octahedron. Other polyhedra have different mathematical relationships between their midsphere and insphere radii.

Q5: What is the significance of the constant √2 in the formula?
A: The constant √2 appears due to the octahedral symmetry and the specific geometric proportions of the Triakis Octahedron.
