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

Bending Stress in Crankweb Due to Tangential Force is the bending stress in the crankweb due to the tangential component of force on connecting rod at crank pin. It is a critical parameter in crankshaft design and analysis.

2. How Does the Calculator Work?

The calculator uses the formula:

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

Where:

\( \sigma_t \) — Bending Stress in Crankweb Due to Tangential Force (Pa)
\( M_{bt} \) — Bending Moment in Crankweb Due to Tangential Force (N·m)
\( t \) — Thickness of Crank Web (m)
\( w \) — Width of Crank Web (m)

Explanation: This formula calculates the bending stress in the crankweb based on the applied bending moment and the geometric properties of the crankweb.

3. Importance of Bending Stress Calculation

Details: Accurate calculation of bending stress is crucial for ensuring the structural integrity and reliability of crankshafts in internal combustion engines and other mechanical systems.

4. Using the Calculator

Tips: Enter bending moment in N·m, thickness and width in meters. All values must be positive and non-zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is the significance of tangential force in crankshaft design?
A: Tangential force is the component of force that contributes to torque generation and causes bending stresses in the crankweb, making it a critical factor in crankshaft design.

Q2: How does crankweb geometry affect bending stress?
A: Both thickness and width of the crankweb significantly influence bending stress. Increasing these dimensions reduces bending stress for a given bending moment.

Q3: What are typical values for bending stress in crankwebs?
A: Acceptable bending stress values depend on the material properties and safety factors used in design, typically ranging from 50-200 MPa for steel crankshafts.

Q4: How is the bending moment Mbt determined?
A: The bending moment is calculated based on the tangential force and the distance from the force application point to the section being analyzed.

Q5: Can this formula be used for other types of stresses?
A: This specific formula is designed for bending stress due to tangential force. Other stress components (radial, torsional) require different calculations.
