Summary
[edit]Description00005 Tavolo di Varignon.jpg |
Italiano: Tavolo circolare verticale per la misurazione delle forze vettoriali tramite lo scomponimento con il parallelogramma. Il tavolo di Varignon è formato da un piatto circolare, mantenuto in posizione orizzontale da un treppiede. Il bordo del piatto è suddiviso in 360° e su di esso sono applicati tre morsetti con carrucole sulle quali si fanno scorrere tre fili uniti tra loro tramite un anello e portanti alle estremità dei pesi variabili due dei quali rappresentano le forze componenti e l’altro la forza risultante.
I morsetti fissano pure sul tavolo il grafico della composizione delle forze disegnato su carta, mentre l’altro anello, che rappresenta il corpo sollecitato dalle forze, viene tenuto nel centro del tavolino mediante uno spillo, che si conficca in un pezzo di sughero fissato nel centro della piattaforma. Trovata la condizione di equilibrio delle tre forze, l’altro anello rimarrà nel centro del tavolino anche dopo aver tolto lo spillo.Creato per dimostrare la somma vettoriale delle forze. |
