1. What is Axial Force?

Axial force is the internal force acting along the longitudinal axis of a structural member. It can be either tensile (pulling) or compressive (pushing) and is calculated as the sum of all forces acting along the axis.

2. How Does the Calculator Work?

The calculator uses the axial force equation:

Where:

• \( F \) — Resultant axial force (N)
• \( \sum F_x \) — Sum of all forces along the axis (N)

Explanation: The calculator sums all input forces and applies the appropriate sign based on the selected direction (tension positive, compression negative).

3. Importance of Axial Force Calculation

Details: Accurate axial force calculation is crucial for structural analysis, determining member stresses, designing connections, and ensuring structural integrity under various loading conditions.

4. Using the Calculator

Tips: Enter force values in Newtons, select the direction (tension or compression). At least one force value is required. The calculator will sum all provided forces.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between tension and compression?
A: Tension stretches or elongates a member, while compression shortens or squeezes it. Tension is typically considered positive, compression negative.

Q2: Can I calculate axial force for multiple forces?
A: Yes, the calculator can sum up to three different forces acting along the same axis.

Q3: What units should I use for force inputs?
A: The calculator expects inputs in Newtons (N), which is the SI unit for force.

Q4: How accurate is this calculation?
A: The calculation provides the theoretical axial force based on the input values. Real-world applications may require additional considerations for factors like eccentric loading or material properties.

Q5: Can this calculator handle negative force values?
A: The calculator automatically applies the appropriate sign based on the direction selection. Input only positive values for forces.
