## Slackline Tension Calculator

You can input quickly with a smartphone.
Of course it is also possible on PC.

Calculate the tension of the slackline from the length/sag/weight.

Calculate direction force and horizontal force.Results for rodeoline & sagline are also practical.The angle is also output.

The weight of the line & backup rope include for super long highline.

### method of calculation

$$T=\frac{BW+\frac{LW}{2}\sqrt{S^2 + (\frac{L}{2})^2}} {2S}$$

T :Tension
BW:Body Weight
LW:Line Weight (total)
L :Line Length
S :Sag

1kgf＝9.81N＝0.00981kN

Special thanks
