STEP 0: Pre-Calculation Summary
Formula Used
Natural Frequency = (Fundamental Vibration Mode/(pi*Cable Span))*sqrt(Cable Tension*[g]/Uniformly Distributed Load)
ωn = (n/(pi*Lspan))*sqrt(T*[g]/q)
This formula uses 2 Constants, 1 Functions, 5 Variables
Constants Used
[g] - Gravitational acceleration on Earth Value Taken As 9.80665
pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288
Functions Used
sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)
Variables Used
Natural Frequency - (Measured in Hertz) - Natural Frequency is the frequency at which a system tends to oscillate in the absence of any driving or damping force.
Fundamental Vibration Mode - Fundamental Vibration Mode is integral value denoting the mode of vibration.
Cable Span - (Measured in Meter) - Cable Span is total length of cable in horizontal direction.
Cable Tension - (Measured in Newton) - Cable Tension is the tension on the cable or the structure at a particular point. (if any random points are considered).
Uniformly Distributed Load - (Measured in Newton per Meter) - Uniformly distributed Load (UDL) is a load that is distributed or spread across the whole region of an element whose magnitude of the load remains uniform throughout the whole element.
STEP 1: Convert Input(s) to Base Unit
Fundamental Vibration Mode: 9.9 --> No Conversion Required
Cable Span: 15 Meter --> 15 Meter No Conversion Required
Cable Tension: 600 Kilonewton --> 600000 Newton (Check conversion ​here)

What is the natural frequency of a system?

Natural frequency, also known as eigenfrequency, is the frequency at which a system tends to oscillate in the absence of any driving or damping force. The motion pattern of a system oscillating at its natural frequency is called the normal mode (if all parts of the system move sinesuoidally with that same frequency).

How to Calculate Natural Frequency of Each Cable?

Natural Frequency of Each Cable calculator uses Natural Frequency = (Fundamental Vibration Mode/(pi*Cable Span))*sqrt(Cable Tension*[g]/Uniformly Distributed Load) to calculate the Natural Frequency, The Natural Frequency of Each Cable formula is defined as the frequency at which the system will vibrate when loaded with dynamic load. Natural Frequency is denoted by ωn symbol.

How to calculate Natural Frequency of Each Cable using this online calculator? To use this online calculator for Natural Frequency of Each Cable, enter Fundamental Vibration Mode (n), Cable Span (Lspan), Cable Tension (T) & Uniformly Distributed Load (q) and hit the calculate button. Here is how the Natural Frequency of Each Cable calculation can be explained with given input values -> 5.096007 = (9.9/(pi*15))*sqrt(600000*[g]/10000).

FAQ

What is Natural Frequency of Each Cable?
The Natural Frequency of Each Cable formula is defined as the frequency at which the system will vibrate when loaded with dynamic load and is represented as ωn = (n/(pi*Lspan))*sqrt(T*[g]/q) or Natural Frequency = (Fundamental Vibration Mode/(pi*Cable Span))*sqrt(Cable Tension*[g]/Uniformly Distributed Load). Fundamental Vibration Mode is integral value denoting the mode of vibration, Cable Span is total length of cable in horizontal direction, Cable Tension is the tension on the cable or the structure at a particular point. (if any random points are considered) & Uniformly distributed Load (UDL) is a load that is distributed or spread across the whole region of an element whose magnitude of the load remains uniform throughout the whole element.
How to calculate Natural Frequency of Each Cable?
