Slackline Tension Calculator
Calculate the tension of the slackline from the length/sag/weight.
Calculate Exact(direction) force.
Longline & rodeoline & sagline are also practical.
The weight of the line & backup rope include for super long highline.

Method of calculation
EXACT line tension
$$T=\frac{B+\frac{E}{2}\sqrt{S^2 + (\frac{H}{2})^2}}
{2S}$$
T :Tension (exact)
B :Body Weight
E :Line Weight (total)
H :Horizontal length
S :Sag
1kgf＝9.81N＝0.00981kN
Horizontal line tension
$$T=\frac{H×(B+\frac{E}{2})}{4S}$$
T :Tension (Horizontal)
B:Body Weight
E :Line Weight (total)
H :Horizontal length
S :Sag
1kgf＝9.81N＝0.00981kN
Exact line length
$$L = 2\sqrt{(\frac{H}{2})^2+S^2}$$
L :Exact line length
H :Horizontal length
S :Sag
Angle of anchor point
$$A = \tan{^{-1}} \frac{S}{\frac{H}{2}}$$
A :Angle of anchor
H :Horizontal length
S :Sag
Angle of middle point
$$M = (90- A)×2$$
M:Angle of middle point
A:Angle of anchor
