1. What is Vertical Reaction at Bearing 3 due to Flywheel?

Vertical Reaction at Bearing 3 due to Flywheel is the vertical reaction force acting on the 3rd bearing of the crankshaft because of the weight of the flywheel. It represents the load distribution in the crankshaft assembly.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ R_{v3} = \frac{W \times c}{c_1} \]

Where:

\( R_{v3} \) — Vertical Reaction at Bearing 3 due to Flywheel (N)
\( W \) — Weight of Flywheel (N)
\( c \) — Centre Crankshaft Bearing2 Gap from Flywheel (m)
\( c_1 \) — Distance Between Bearing 2&3 of Centre Crankshaft (m)

Explanation: The formula calculates the vertical reaction force at bearing 3 based on the principle of moments and force distribution in the crankshaft system.

3. Importance of Vertical Reaction Calculation

Details: Accurate calculation of vertical reactions is crucial for proper crankshaft design, bearing selection, and ensuring structural integrity of the engine assembly under various loading conditions.

4. Using the Calculator

Tips: Enter flywheel weight in Newtons, bearing gap and distance in meters. All values must be positive and non-zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: Why is vertical reaction at bearing 3 important?
A: It helps determine the load distribution on crankshaft bearings, which is essential for proper bearing design and ensuring longevity of the engine components.

Q2: What factors affect the vertical reaction force?
A: The force depends on the flywheel weight, the distance between bearings, and the position of the flywheel relative to the bearings.

Q3: How does this calculation relate to TDC position?
A: At Top Dead Center position, the forces are typically at their maximum, making this calculation critical for worst-case scenario design.

Q4: Are there any limitations to this formula?
A: This formula provides a simplified static analysis and may need to be combined with dynamic analysis for complete crankshaft design.

Q5: Can this calculator be used for other bearing positions?
A: This specific calculator is designed for bearing 3. Different formulas would be needed for reactions at other bearing positions.
