1. What is Torsional Moment at Crankshaft Under Flywheel?

The Torsional Moment at Crankshaft Under Flywheel is the torsional moment induced at the central plane of the crankshaft below the flywheel when an external twisting force is applied to the crankshaft. It represents the twisting force that the crankshaft experiences during operation.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( M_t \) — Torsional Moment at Crankshaft Under Flywheel (N·m)
• \( P_t \) — Tangential Force at Crank Pin (N)
• \( r \) — Distance Between Crank Pin And Crankshaft (m)

Explanation: The torsional moment is calculated by multiplying the tangential force at the crank pin by the perpendicular distance between the crank pin and the crankshaft.

3. Importance of Torsional Moment Calculation

Details: Accurate calculation of torsional moment is crucial for crankshaft design, stress analysis, and ensuring the structural integrity of engine components under maximum torque conditions.

4. Using the Calculator

Tips: Enter the tangential force at crank pin in Newtons (N) and the distance between crank pin and crankshaft in meters (m). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is tangential force at crank pin?
A: Tangential force at crank pin is the component of thrust force on the connecting rod acting at the crankpin in the direction tangential to the connecting rod.

Q2: Why is this calculation important for engine design?
A: This calculation helps engineers determine the torsional stresses in the crankshaft, which is essential for designing a crankshaft that can withstand operational loads without failure.

Q3: What units should be used for input values?
A: Tangential force should be in Newtons (N) and distance should be in meters (m) for consistent SI unit results.

Q4: When is maximum torsional moment typically experienced?
A: Maximum torsional moment typically occurs at maximum torque conditions when the engine is producing its peak twisting force.

Q5: How does this relate to flywheel design?
A: The torsional moment calculation helps determine the appropriate flywheel size and design to smooth out torque fluctuations and maintain engine stability.
