DISCLAIMER: I do not claim that the results of this calculator are accurate or relevant to any real-world scenario. They are based on an assumption that may very well be flagrantly incorrect. If you use these calculations for anything, you do so at your own risk.

This calculator uses the results of this paper to compute various forces involved in slacklining.

Please enter the following information. You may use any units of measurement that you like, as long as you use the same units for all of the lengths. See the diagram above for clarification on any of the variables.
Length of line (D):
(This refers to the horizontal distance between the anchors, not the length of webbing used.)
Horiz. dist. from anchor to person (x0):
Depression of line (Δ):
Weight of person (mg):
(You may use lbs, kg, N, kN, or whatever unit of force you prefer for this. Just be aware that the forces below will be in the same units. Alternatively, you can leave this blank or enter 1 to get results as a multiple of bodyweight.)

If you wish to consider the effects of a leash fall, enter the following information. If not, you may leave these blank.
