K tomu programu patrí rovnaký komentár ako ku Skrutka.pas. Vie vypoèítava» predpäté spoje podµa ÈSN 014216-65. Komu to niè nehovorí tak napríklad nahrejeme ozubené koleso a nasuniete na hriadeµ. A¾ vychladne, zmen¹í sa, a vytvorí nerozoberateµný spoj. No a koµko tento spoj vydr¾í v krute vie program vypoèíta».
