1. What is Tensile Force on Bolt?

The 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, determining the bolt's ability to withstand pulling forces without failure.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ P = (\pi \times \tau \times d_c' \times h_n) \]

Where:

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

Explanation: This formula calculates the tensile force that a bolt can withstand based on the shear stress it experiences, its core diameter, and the height of the nut.

3. Importance of Tensile Force Calculation

Details: Accurate tensile force calculation is crucial for ensuring bolt integrity in various applications, from construction and automotive to aerospace industries. It helps prevent bolt failure under load.

4. Using the Calculator

Tips: Enter shear stress in pascals (Pa), core diameter in meters (m), and height of nut in meters (m). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

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

Q2: How does shear stress affect bolt strength?
A: Shear stress represents the force tending to cause deformation of the bolt by slippage along parallel planes, directly impacting the bolt's tensile capacity.

Q3: Why is nut height important in this calculation?
A: The height of the nut affects the engagement length of the threads, which influences the distribution of stress and the overall strength of the connection.

Q4: What units should I use for input values?
A: Use pascals (Pa) for shear stress, and meters (m) for both core diameter and nut height to get results in newtons (N).

Q5: Can this formula be used for all types of bolts?
A: This formula is generally applicable to standard threaded bolts, but special bolt designs or materials may require additional considerations.
