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

Bending Stress in Crankweb Due to Tangential Force is the stress developed in the crankweb due to the tangential component of force acting on the connecting rod at the crank pin. This stress is crucial in determining the structural integrity of the crankshaft under maximum torque conditions.

2. How Does the Calculator Work?

The calculator uses the formula:

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

Where:

\( \sigma_{bt} \) — 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 based on the bending moment and the geometric properties of the crank web.

3. Importance of Bending Stress Calculation

Details: Accurate calculation of bending stress is essential for designing crankshafts that can withstand the maximum torque conditions without failure, ensuring reliability and safety in engine operation.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What units should be used for input values?
A: Bending moment should be in Newton-meters (N·m), thickness and width in meters (m).

Q2: Why is bending stress important in crankshaft design?
A: Bending stress helps determine if the crankshaft can withstand operational loads without excessive deformation or failure.

Q3: What factors affect bending stress in crankweb?
A: The magnitude of tangential force, geometry of the crank web, and material properties influence the bending stress.

Q4: How can bending stress be reduced?
A: Increasing the thickness or width of the crank web, or using materials with higher strength can reduce bending stress.

Q5: Is this formula applicable to all types of crankshafts?
A: This formula is specifically for side crankshafts under tangential thrust for maximum torque conditions.
