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

Vertical Reaction at Bearing 2 due to Flywheel Weight is the vertical reaction force acting on the 2nd bearing of the crankshaft because of the weight of the flywheel. This calculation is essential for proper crankshaft design and bearing selection.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ R_{f2} = \frac{c_1 \times W}{c} \]

Where:

\( R_{f2} \) — Vertical Reaction at Bearing 2 due to Flywheel (N)
\( c_1 \) — Side Crankshaft Bearing1 gap from Flywheel (m)
\( W \) — Weight of Flywheel (N)
\( c \) — Distance Between Bearing1&2 of Side Crankshaft (m)

Explanation: The formula calculates the vertical reaction force at the second bearing based on the principle of moments and force 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 the structural integrity of the engine assembly. It helps prevent premature bearing failure and ensures optimal engine performance.

4. Using the Calculator

Tips: Enter all distances in meters (m) and weight in Newtons (N). All values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: Why is this calculation important for engine design?
A: This calculation helps determine the load distribution on crankshaft bearings, which is essential for selecting appropriate bearings and ensuring proper engine operation.

Q2: What units should be used for input values?
A: All distances should be in meters (m) and weight/force values in Newtons (N) for consistent results.

Q3: How does flywheel weight affect bearing reactions?
A: Heavier flywheels create higher reaction forces on the bearings, requiring stronger bearing designs and potentially affecting engine vibration characteristics.

Q4: Can this formula be used for other similar calculations?
A: Yes, this basic principle of moments can be applied to various similar engineering problems involving force distribution in supported structures.

Q5: What factors besides flywheel weight affect bearing reactions?
A: Other factors include engine torque, piston forces, connecting rod forces, and dynamic effects from engine operation at different speeds.
