Lorenzo, tramite la fune d’acciaio del verricello montato sul frontale del suo fuoristrada, vuole trascinare un tronco d’albero con massa di 3,00 quintali poggiato su un terreno la cui superficie è inclinata di 30,0° rispetto all’orizzontale. Considera il fuoristrada fermo in alto sul terreno orizzontale, la fune parallela al terreno in pendio e l’albero in basso nel pendio. Si trascurino le forze di attrito. Calcola la forza minima che il verricello deve esercitare per poter trascinare il tronco. Es. di notazione scientifica: 3,2x10^4 *
