Span of Cable for Length of Cable for UDL on Parabolic Cable Solution

STEP 0: Pre-Calculation Summary

Formula Used

Length of Cable Span = 1.5*Length of Cable-sqrt((2.25*Length of Cable^2)-8*(Maximum Sag^2))
L_{cable_span} = 1.5*L-sqrt((2.25*L^2)-8*(d^2))
This formula uses 1 Functions, 3 Variables

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

Length of Cable Span - (Measured in Meter) - Length of cable span is total length of cable in horizontal direction.
Length of Cable - (Measured in Meter) - Length of Cable is the length of tendon used for prestressing in the concrete section.
Maximum Sag - (Measured in Meter) - Maximum Sag is the maximum catenary or the greatest amount of sag that can be allowed in the cable system.

STEP 1: Convert Input(s) to Base Unit

Length of Cable: 50 Meter --> 50 Meter No Conversion Required
Maximum Sag: 1.44 Meter --> 1.44 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L_{cable_span} = 1.5*L-sqrt((2.25*L^2)-8*(d^2)) --> 1.5*50-sqrt((2.25*50^2)-8*(1.44^2))

Evaluating ... ...

L_{cable_span} = 0.110673657723424

STEP 3: Convert Result to Output's Unit

0.110673657723424 Meter --> No Conversion Required

FINAL ANSWER

0.110673657723424 ≈ 0.110674 Meter <-- Length of Cable Span

Tension at Midspan given Tension at Supports for UDL on Parabolic Cable

Go Tension at Midspan = sqrt((Tension at Supports^2)-(((Uniformly Distributed Load*Cable Span)/2)^2))

UDL given Tension at Supports for UDL on Parabolic Cable

Go Uniformly Distributed Load = (sqrt((Tension at Supports^2)-(Tension at Midspan^2))*2)/Cable Span

Tension at Supports for UDL on Parabolic Cable

Go Tension at Supports = sqrt((Tension at Midspan^2)+(Uniformly Distributed Load*Cable Span/2)^2)

Maximum Sag given Tension at Midspan for UDL on Parabolic Cable

Go Maximum Sag = Uniformly Distributed Load*(Cable Span^2)/(8*Tension at Midspan)

Span of Cable for Length of Cable for UDL on Parabolic Cable Formula

Length of Cable Span = 1.5*Length of Cable-sqrt((2.25*Length of Cable^2)-8*(Maximum Sag^2))
L_{cable_span} = 1.5*L-sqrt((2.25*L^2)-8*(d^2))
