1. What is Tension at Supports?

Tension at Supports refers to the force exerted on the supporting structures due to loading on the cable system. It is a critical parameter in cable structure design and analysis.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T_s \) — Tension at Supports (N)
• \( d \) — Maximum Sag (m)
• \( c \) — Catenary Parameter (m)
• \( q \) — Uniformly Distributed Load (N/m)

Explanation: The formula calculates the tension at supports by summing the maximum sag and catenary parameter, then multiplying by the uniformly distributed load.

3. Importance of Tension Calculation

Details: Accurate tension calculation is crucial for structural design, ensuring cable systems can withstand applied loads while maintaining safety margins and structural integrity.

4. Using the Calculator

Tips: Enter maximum sag and catenary parameter in meters, and uniformly distributed load in N/m. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is maximum sag in cable systems?
A: Maximum sag is the greatest vertical displacement or droop that occurs in a cable under load, typically at the midpoint between supports.

Q2: How is catenary parameter defined?
A: Catenary parameter is a factor that accounts for the increase in load due to the cable's self-weight and the resulting catenary shape.

Q3: What types of structures use this calculation?
A: This calculation is commonly used in suspension bridges, overhead power lines, cable-stayed structures, and other cable-supported systems.

Q4: Are there limitations to this formula?
A: This formula assumes ideal conditions and may need adjustments for complex loading scenarios, temperature variations, or non-uniform cable properties.

Q5: How does uniformly distributed load affect tension?
A: Higher uniformly distributed loads directly increase the tension at supports, requiring stronger support structures and cable materials.
