Az elhangzó szöveg
A hengerre ható gravitációt, a Föld vonzóerejét a felfüggesztő fonal képes ellensúlyozni, nem szakad el. Az ugyanolyan anyagból való 3 fonaldarab együtt háromszor akkora terhelést képes elviselni szakadás nélkül, mint a felső fonal. Egy erőteljes, hirtelen rántás hatására mégis a három fonál szakad el. Ha az erőkifejtés nem hirtelen, rövid idő alatt történik, hanem ráérősen, fokozatosan növeljük a lefelé irányuló húzóerőt, akkor a felső fonal fog elszakadni, hiszen azt még a henger súlya is terheli.
Inertia I.
The gravitation, i.e. the attraction of the Earth, acting on a cylinder is balanced by the suspension string, which is not torn. Three pieces of strings made of the same material can sustain three times as large weight as the upper string. Yet under a strong sudden duress the three strings will be torn. If the effect is not sudden but the pulling force is increased gradually, the upper string will be torn since that is strained by the weight of the cylinder as well.
