1. What is the Diameter of Circular Shaft Formula?

The formula calculates the diameter of a circular shaft given its section modulus. The section modulus is a geometric property that indicates a beam's resistance to bending stress.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \Phi \) — Diameter of circular shaft (m)
• \( Z \) — Section modulus (m³)
• \( \pi \) — Archimedes' constant (approximately 3.14159)

Explanation: This formula derives from the relationship between the section modulus and the geometric properties of a circular cross-section.

3. Importance of Diameter Calculation

Details: Calculating the appropriate diameter is crucial for structural design to ensure beams and shafts can withstand applied loads without excessive bending or failure.

4. Using the Calculator

Tips: Enter the section modulus value in cubic meters (m³). The value must be greater than zero for valid calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is section modulus?
A: Section modulus is a geometric property that represents a beam's resistance to bending. It's calculated based on the cross-sectional shape and dimensions.

Q2: Why is the diameter calculation important?
A: Proper diameter calculation ensures structural components can handle expected loads without deformation or failure, which is critical for safety and performance.

Q3: What units should be used?
A: Section modulus should be in cubic meters (m³) for consistent results. The calculated diameter will be in meters (m).

Q4: Are there limitations to this formula?
A: This formula applies specifically to solid circular cross-sections. Different formulas are needed for hollow circular sections or other shapes.

Q5: How accurate is this calculation?
A: The calculation is mathematically exact for the given formula. Accuracy depends on the precision of the input section modulus value.
