1. What is Cable Tension for UDL?

Cable Tension for UDL refers to the total tension developed in a cable when subjected to a uniformly distributed load across its entire span. This calculation is essential in structural engineering for designing cable-supported structures.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ T_{cable\ udl} = \frac{q \times L_{span}^2}{8 \times f} \]

Where:

\( T_{cable\ udl} \) — Cable Tension for UDL (N)
\( q \) — Uniformly Distributed Load (N/m)
\( L_{span} \) — Cable Span (m)
\( f \) — Sag of Cable at Midway between Supports (m)

Explanation: The formula calculates the horizontal component of cable tension based on the distributed load, cable span length, and the sag at the midpoint of the cable.

3. Importance of Cable Tension Calculation

Details: Accurate cable tension calculation is crucial for designing safe and efficient cable-supported structures such as suspension bridges, cable-stayed bridges, and overhead transmission lines. It ensures structural integrity and prevents cable failure.

4. Using the Calculator

Tips: Enter uniformly distributed load in N/m, cable span in meters, and sag at midpoint in meters. All values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is a uniformly distributed load?
A: A uniformly distributed load is a load that is spread evenly across the entire length of the cable, maintaining constant magnitude throughout.

Q2: How does cable sag affect tension?
A: Greater sag reduces cable tension, while smaller sag increases tension. There's an inverse relationship between sag and tension in the cable.

Q3: What units should be used for input values?
A: Use Newtons per meter (N/m) for distributed load, meters (m) for cable span, and meters (m) for sag measurement.

Q4: Is this formula applicable to all cable types?
A: This formula applies to ideal flexible cables with uniform cross-section that carry only axial tension and have small sag-to-span ratios.

Q5: What are typical applications of this calculation?
A: This calculation is used in designing suspension bridges, overhead power lines, cable car systems, and other cable-supported structures.
