tether_tension_fixed — DRIVE `kendama` op

• Data kinds: none → scalar (an op determined by its arguments alone — it takes no image or data input)

• Call: import fullseye as fs; fs.ledger.tether_tension_fixed(v: 'float', theta: 'float', L: 'float', mass: 'float', g: 'float' = 9.81) -> 'float' (to call the implementation directly, import kendama; kendama.tether_tension_fixed(v: 'float', theta: 'float', L: 'float', mass: 'float', g: 'float' = 9.81) -> 'float'; from the registry, opsdrive.get("tether_tension_fixed"))

Usage

Tension T = m(v²/L + g cos θ) of an inextensible string with a fixed hand end (v = speed, θ = angle from straight down). If negative, "a string cannot push" = it goes slack.
