1. What is Bending Moment in Crankweb Due to Tangential Force?

The bending moment in crankweb due to tangential force is the bending moment in the crankweb caused by the tangential component of force on the connecting rod at the crank pin. This is a critical parameter in crankshaft design and analysis.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ M_{bt} = \frac{\sigma_{bt} \times t \times w^2}{6} \]

Where:

\( M_{bt} \) — Bending moment in crankweb due to tangential force (N·m)
\( \sigma_{bt} \) — Bending stress in crankweb due to tangential force (Pa)
\( t \) — Thickness of crank web (m)
\( w \) — Width of crank web (m)

Explanation: This formula calculates the bending moment based on the bending stress and the geometric properties of the crank web.

3. Importance of Bending Moment Calculation

Details: Accurate calculation of bending moment is crucial for designing crankshafts that can withstand operational stresses, ensuring structural integrity and preventing mechanical failures.

4. Using the Calculator

Tips: Enter bending stress in Pascals (Pa), thickness and width in meters (m). All values must be positive and valid for accurate results.

5. Frequently Asked Questions (FAQ)

Q1: What is the significance of tangential force in crankshaft design?
A: Tangential force is the component that produces torque in the crankshaft, making it a critical factor in power transmission and structural design.

Q2: How does crank web geometry affect bending moment?
A: Both thickness and width of the crank web significantly influence the bending moment capacity, with width having a squared relationship in the calculation.

Q3: What are typical values for bending stress in crankwebs?
A: Bending stress values vary based on material properties and design specifications, typically ranging from 50-200 MPa for steel crankshafts.

Q4: When is this calculation most critical?
A: This calculation is particularly important during maximum torque conditions when tangential forces reach their peak values.

Q5: How does this relate to overall crankshaft design?
A: The bending moment calculation is part of comprehensive crankshaft analysis that includes torsional stresses, fatigue analysis, and dynamic loading considerations.
