1. What is Tensile Force on Bolt?

Tensile Force on Bolt is the magnitude of the force applied along the bolt axis trying to stretch the bolt. It is a critical parameter in mechanical engineering and structural design.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P \) — Tensile Force on Bolt (N)
• \( \pi \) — Archimedes' constant (≈3.1416)
• \( \tau \) — Shear Stress in Bolt (Pa)
• \( d_c' \) — Core Diameter of Threaded Bolt (m)
• \( h_n \) — Height of Nut (m)

Explanation: This formula calculates the tensile force acting on a bolt based on shear stress, core diameter, and nut height.

3. Importance of Tensile Force Calculation

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

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is the core diameter of a threaded bolt?
A: Core diameter is defined as the smallest diameter of the thread of the bolt, also known as the minor diameter.

Q2: How does shear stress affect tensile force?
A: Shear stress is directly proportional to tensile force - higher shear stress results in higher tensile force for the same bolt dimensions.

Q3: What units should be used for input values?
A: Use Pascals for shear stress, and meters for both core diameter and height of nut to get results in Newtons.

Q4: Are there limitations to this formula?
A: This formula provides an estimate and may need adjustment for specific bolt materials, thread types, or extreme loading conditions.

Q5: Can this calculator be used for all bolt types?
A: While the formula is generally applicable, specific bolt designs and materials may require additional considerations for accurate force calculations.
