1. What is Section Modulus of Crankweb?

The Section Modulus of Crankweb is a geometric property that represents the ratio of the moment of inertia about the neutral axis to the distance of the extreme fiber from the neutral axis. It is a crucial parameter in determining the bending stress capacity of the crankweb in a centre crankshaft under maximum torque conditions.

2. How Does the Calculator Work?

The calculator uses the section modulus formula:

\[ Z = \frac{w \times t^2}{6} \]

Where:

\( Z \) — Section Modulus of Crankweb (m³)
\( w \) — Width of Crank Web (m)
\( t \) — Thickness of Crank Web (m)

Explanation: The formula calculates the section modulus for a rectangular cross-section, which is essential for determining the bending stress capacity of the crankweb under maximum torque conditions.

3. Importance of Section Modulus Calculation

Details: Accurate section modulus calculation is crucial for designing crankshafts that can withstand maximum torque without failure. It helps engineers determine the appropriate dimensions of the crankweb to ensure structural integrity and optimal performance.

4. Using the Calculator

Tips: Enter the width and thickness of the crankweb in meters. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: Why is section modulus important in crankshaft design?
A: Section modulus determines the bending stress capacity of the crankweb, which is critical for ensuring the crankshaft can withstand maximum torque without structural failure.

Q2: What units should I use for input values?
A: The calculator uses meters (m) for both width and thickness measurements to maintain consistency with SI units.

Q3: How does section modulus relate to bending stress?
A: Bending stress is calculated by dividing the bending moment by the section modulus (σ = M/Z). A higher section modulus results in lower bending stress for the same bending moment.

Q4: Are there limitations to this formula?
A: This formula is specifically for rectangular cross-sections. For complex geometries, more advanced calculations or finite element analysis may be required.

Q5: Can this calculator be used for other applications?
A: While designed for crankweb calculations, the formula applies to any rectangular cross-section where section modulus needs to be determined.
