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. This stress is critical in designing and analyzing crankshafts for internal combustion engines.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \sigma_{bt} = \frac{6 \times P_t \times (r - \frac{d_1}{2})}{t \times w^2} \]

Where:

\( \sigma_{bt} \) — Bending Stress in Crankweb Due to Tangential Force (Pa)
\( P_t \) — Tangential Force at Crank Pin (N)
\( r \) — Distance Between Crank Pin And Crankshaft (m)
\( d_1 \) — Diameter of Journal or Shaft at Bearing 1 (m)
\( t \) — Thickness of Crank Web (m)
\( w \) — Width of Crank Web (m)

Explanation: The formula calculates the bending stress in the crankweb caused by the tangential force acting at the crank pin, considering the geometry of the crankshaft.

3. Importance of Bending Stress Calculation

Details: Accurate calculation of bending stress is crucial for ensuring the structural integrity and fatigue life of crankshafts. It helps in determining whether the crankshaft can withstand the operational loads without failure.

4. Using the Calculator

Tips: Enter all values in SI units. Ensure that all inputs are positive values. The calculator will compute the bending stress in Pascals (Pa).

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. It is critical for power transmission and causes bending stresses in the crankweb.

Q2: How does crankweb geometry affect bending stress?
A: The thickness and width of the crankweb directly influence the bending stress. Thicker and wider crankwebs generally result in lower bending stresses.

Q3: What are typical values for bending stress in crankwebs?
A: Acceptable bending stress values depend on the material properties. For steel crankshafts, bending stresses are typically kept below the material's yield strength with appropriate safety factors.

Q4: Can this calculator be used for all types of crankshafts?
A: This formula is specifically designed for side crankshafts under maximum torque conditions. Other crankshaft configurations may require different calculations.

Q5: What units should be used for input values?
A: All input values should be in SI units: Newtons (N) for force and meters (m) for distances and dimensions.
