1. What is External Force On Bolt?

External Force on Bolt is defined as the forces caused by an external agent present outside of the system. It represents the total external load acting on a bolted joint assembly.

2. How Does the Calculator Work?

The calculator uses the External Force on Bolt formula:

Where:

• \( P_e \) — External Force on Bolt (Newton)
• \( n \) — Number of Bolts in Joint
• \( P_1' \) — Primary Shear Load on Bolt (Newton)

Explanation: The equation calculates the total external force by multiplying the number of bolts in the joint by the primary shear load acting on each individual bolt.

3. Importance of External Force Calculation

Details: Accurate calculation of external force on bolts is crucial for proper joint design, ensuring structural integrity, and preventing joint failure under load conditions.

4. Using the Calculator

Tips: Enter the number of bolts in the joint and the primary shear load on each bolt. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is primary shear load on a bolt?
A: Primary shear load is defined as the force acting in a direction parallel to a surface or to a planar cross-section of the bolt.

Q2: How does the number of bolts affect the external force?
A: The external force is directly proportional to the number of bolts - more bolts can distribute and handle greater external loads.

Q3: When should this calculation be used?
A: This calculation is essential during the design phase of bolted joints to ensure proper load distribution and joint strength.

Q4: Are there limitations to this equation?
A: This equation assumes uniform load distribution among all bolts, which may not always be the case in practical applications.

Q5: What units should be used for input values?
A: The primary shear load should be in Newtons, and the number of bolts is a dimensionless count.
