Abstract
The contribution describes some aspects related to the representation of special curves; recalling mechanisms created specifically for the design of these curves, which have particular characteristics. Through the construction of a simple apparatus, consisting of two pendulums-which oscillate at the same time- it is possible to graphically reproduce Lissajous' experiments on the commuting vibrations of the diapasons. This equipment was first built by Samuel Charles Tisley (London 1829-Unknown), under the name of harmonographer. The contribution aslo illustrates the essential characteristics of the harmonograph-born as a means of analysing vibrations-but which, by its principle belongs to mechanics, for its applications to acoustic science and geometry for the ability to draw "harmonious" curves.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
