The Gatenary
Equation
The curve
formed by
suspendit
g a
flexible
cable
from two
points
is
called
a
catenary,
and
is
defined
by the
equation:
y
:
a cosh
(x/
a)
The length
of the
cable
is
calculated
by
the
equation:
L
:
2a
sinh (x/a)
where a is the lowest height
of
the cable and L is the
cable length.
