1. What is the Inner Circle Radius of Annulus?

The Inner Circle Radius of Annulus is the radius of its cavity and it is the smaller radius among two concentric circles. An annulus is the region between two concentric circles, resembling a ring or a washer.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( r_{Inner} \) — Inner Circle Radius of Annulus (m)
• \( P \) — Perimeter of Annulus (m)
• \( b \) — Breadth of Annulus (m)
• \( \pi \) — Archimedes' constant (approximately 3.14159)

Explanation: This formula calculates the inner radius of an annulus using its perimeter and breadth, taking into account the mathematical relationship between these geometric properties.

3. Importance of Inner Radius Calculation

Details: Calculating the inner radius of an annulus is important in various engineering and design applications, particularly in mechanical engineering, architecture, and manufacturing where annular shapes are commonly used.

4. Using the Calculator

Tips: Enter the perimeter and breadth of the annulus in meters. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is an annulus?
A: An annulus is a ring-shaped object, the region bounded by two concentric circles of different radii.

Q2: How is the perimeter of an annulus calculated?
A: The perimeter of an annulus is the sum of the circumferences of both the outer and inner circles.

Q3: What is the breadth of an annulus?
A: The breadth of an annulus is the difference between the outer and inner radii.

Q4: Can this formula be used for any annulus?
A: Yes, this formula applies to all annular shapes where the inner and outer circles are concentric.

Q5: What are practical applications of annulus calculations?
A: Annulus calculations are used in pipe design, bearing manufacturing, architectural elements, and various mechanical components.
