Maximum Sag given Length of Cable for UDL on Parabolic Cable Solution

STEP 0: Pre-Calculation Summary

Formula Used

Maximum Sag = sqrt((Cable Length-Cable Span)*(3/8)*Cable Span)
d = sqrt((S_cable-L_span)*(3/8)*L_span)
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

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.
Cable Length - (Measured in Meter) - Cable Length is the length measured along the catenary of cable.
Cable Span - (Measured in Meter) - Cable Span is total length of cable in horizontal direction.

STEP 1: Convert Input(s) to Base Unit

Cable Length: 40.6 Meter --> 40.6 Meter No Conversion Required
Cable Span: 15 Meter --> 15 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

d = sqrt((S_cable-L_span)*(3/8)*L_span) --> sqrt((40.6-15)*(3/8)*15)

Evaluating ... ...

d = 12

STEP 3: Convert Result to Output's Unit

12 Meter --> No Conversion Required

FINAL ANSWER

12 Meter <-- Maximum Sag
