1. What is Tensile Force in Bolt?

Tensile Force in Bolt is the stretching force acting on the bolt and generally results in tensile stress and tensile strain in the specimen. It's a critical parameter in bolted joint design and analysis.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \pi \) — Archimedes' constant (approximately 3.1416)
• \( Core\ Diameter\ of\ Bolt \) — Smallest diameter of the thread of the bolt (m)
• \( Height\ of\ Nut \) — Height of the nut used in fitting to the bolt (m)
• \( Shear\ Yield\ Strength\ of\ Bolt \) — Strength of the bolt against shear failure (Pa)
• \( Factor\ of\ Safety\ of\ Bolted\ Joint \) — Safety factor expressing joint strength margin

Explanation: This formula calculates the tensile force that a bolt can withstand in shear conditions, considering material properties and safety factors.

3. Importance of Tensile Force Calculation

Details: Accurate tensile force calculation is crucial for ensuring bolted joint integrity, preventing mechanical failures, and maintaining structural safety in various engineering applications.

4. Using the Calculator

Tips: Enter core diameter and height of nut in meters, shear yield strength in Pascals, and factor of safety. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is core diameter of bolt?
A: Core diameter is the smallest diameter of the bolt thread, also known as minor diameter in threading terminology.

Q2: Why is factor of safety important?
A: Factor of safety accounts for uncertainties in material properties, manufacturing variations, and unexpected loading conditions.

Q3: What units should be used for input values?
A: Use meters for length dimensions, Pascals for strength values, and dimensionless number for factor of safety.

Q4: When is this calculation particularly important?
A: This calculation is critical in structural engineering, mechanical design, and any application where bolted joints experience significant shear loads.

Q5: How does shear yield strength affect the result?
A: Higher shear yield strength allows the bolt to withstand greater tensile forces before yielding in shear, making material selection crucial.
