1. What is Vertical Reaction at Bearing 2 Due to Flywheel?

Vertical Reaction at Bearing 2 Due to Flywheel is the vertical reaction force acting on the 2nd 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:

\[ R'_{2v} = \frac{W \times c_2}{c} \]

Where:

\( R'_{2v} \) — Vertical Reaction at Bearing 2 Due to Flywheel (N)
\( W \) — Weight of Flywheel (N)
\( c_2 \) — Centre Crankshaft Bearing3 Gap from Flywheel (m)
\( c \) — Gap Between Bearing 2&3 of Centre Crankshaft (m)

Explanation: This formula calculates the vertical reaction force at bearing 2 based on the principle of moments and load distribution in a simply supported beam system.

3. Importance of Vertical Reaction Calculation

Details: Accurate calculation of bearing reactions is crucial for proper crankshaft design, bearing selection, and ensuring structural integrity under maximum torque conditions.

4. Using the Calculator

Tips: Enter flywheel weight in Newtons, bearing gaps in meters. All values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: Why is this calculation important in crankshaft design?
A: It helps determine the load distribution on bearings, which is essential for selecting appropriate bearing sizes and ensuring proper lubrication under maximum torque conditions.

Q2: What factors affect the vertical reaction force?
A: The reaction force depends on the flywheel weight and the relative positions of the bearings along the crankshaft.

Q3: How does maximum torque affect bearing reactions?
A: At maximum torque, the crankshaft experiences the highest loading conditions, making accurate reaction force calculations critical for durability and reliability.

Q4: Are there any limitations to this calculation?
A: This calculation assumes static loading conditions and may need to be combined with dynamic analysis for complete crankshaft design.

Q5: How is this result used in engineering practice?
A: Engineers use this calculation to verify bearing capacity, check stress levels, and ensure the crankshaft assembly can withstand operational loads.
