U Cavendishovom eksperimentu kojim se odrejduje gravitacijska konstanta G,
Cavendishovo njihalo visi na 1/1000 inca odnosno otprilike
0.025 mm tankoj zici od volframa zato jer volfram ima jako malu torziju.
Mene zanima gdje nabaviti tako tanku zicu od volframa ili barem da mi netko
preporuci kakvu zicu i kojeg promjera da uzmem umjesto te volframove za to
njihalo. Najtanja koju sam mogao nabaviti je bakrena 0.04mm promjera zica.
Da li bi ta zica bila dobra, ili koje modifikacije bi tregao napraviti na
njihalu da to funkcionira.
