tacsim op• Data kinds: scalar × scalar × scalar → table
• Call: import fullseye as fs; fs.ledger.hertz_cylinder(F_per_L: 'float', R: 'float', Estar: 'float') -> 'dict' (to call the implementation directly, import tacsim; tacsim.hertz_cylinder(F_per_L: 'float', R: 'float', Estar: 'float') -> 'dict'; from the registry, opsdrive.get("hertz_cylinder"))

円柱(半径 R)を弾性半空間に線荷重 F/L で押す線接触(Johnson 1985 §4.2): 接触半幅 b = √(4(F/L)R/(πE*))、p0 = 2(F/L)/(πb)。
返り: `b、p0、pm` = (F/L)/(2b) = (π/4)p0、入力。2-D の押し込み δ は対数的で参照点に依存するため返さない。
Raises `ValueError`: ≤ 0。
