Cable Sag Error (Catenary Curve Effect) Calculator

A displacement cable is best described by a catenary curve when the curve is subjected to a uniform force. The curve effect resembles a flexible chain suspended by its ends with gravity acted upon it. This simple online calculator calculates the cable sag measurement error and the length.

Formula Used:

q = w * g,
a = n / q,
h = a ( cosh ( l / ( 2* a )) - 1),
s = 2 * a * sinh ( l / ( 2* a ))

 Where,
q = cable weight per unit length,
w = cable mass per unit length,
g = force perpendicular to cable length,
a = angle between x axis and cable sector,
n = cable tension,
l = straight line distance,
h = cable sag,
s = cable length.
