Cable Force Calculator

Tools - Pcbcupid - Easy and the most simplified Cable Force Calculator

The amount of tension or pulling force applied to cables and wires in electrical and electronic systems is referred to as cable force.
It is essential for preserving the cables’ structural soundness and dependability and avoiding drooping, distortion, or mechanical failure.

Ensuring the efficient and safe operation of electrical and electronic systems is the main goal of cable force management.
An excessive amount of tension on cables can cause performance problems, signal deterioration, or even damage to the equipment. Proper cable force helps to avoid this.

Determines the cable’s tension at the ends that are supported. The tension exerted to the two supported ends of the cable is referred to as “force” and has the potential to cause the object to deform or accelerate. It is crucial to confirm that the cable tension can withstand the stress brought on by the weight of the object. The calculator allows users to enter the necessary information in order to calculate the cable force at the support ends.

Understanding Cable Force:

Pretensioning, which is putting a specific amount of tension on the cable to lessen moments in the structure, can create cable force.

There are several ways to compute cable force, including formulas and simulations.

The process of cable force optimization entails determining the ideal cable force in order to produce the required structural behavior.

Numerous variables, such as the kind of cable material, the cable’s diameter and length, and the environment in which it is used, can have an impact on cable force.

All things considered, Cable Force is a crucial idea in several disciplines, including as materials science, structural engineering, and electrical engineering. Designing and improving systems that depend on cables or wires to transfer power or support structures requires an understanding of cable force.

Midspan Force in Cable (H)
Unit Load (w)
Cable Span (L)


\[T= \sqrt{H^2 +\left(\frac{w×L}{2} \right)^2}\] ​

where :

  • T = Force in Cable at Support Ends
  • H = Midspan Force in Cable
  • w = Unit Load
  • L = Cable Span
