Il termine\u00a0bilancia\u00a0deriva dal latino\u00a0\u201cbilanx\u201d\u00a0che significa \u201ca due piatti\u201d. Essa \u00e8 uno degli strumenti pi\u00f9 antichi inventati dall&#8217;uomo: se ne conservano esemplari databili al V sec. a.C. Il suo funzionamento \u00e8 basato sul principio della leva: \u00e8 costituita da un giogo che pu\u00f2 oscillare attorno ad un fulcro, recante alle estremit\u00e0 due piatti. La pesata avviene mediante confronto tra pesi campione di massa nota e l\u2019oggetto di massa ignota. Gli spostamenti dalla posizione di equilibrio vengono segnalati dall&#8217;indice su una scala graduata. <\/p>\n\n\n\n<p><strong>GB<\/strong> &#8211; Analytical weight scale with equal arms &#8211; The analytical weight scale (or \u201cbalances\u201d) with equal arms is a mass measurement instrument, with a high degree of precision. It is enclosed in a transparent container (which can be opened), so that dust cannot enter, and air currents do not distort the measurement. The term weight \u201cbalances\u201d comes from the Latin &#8220;bilanx&#8221; which means &#8220;two plates&#8221;. It is one of the most ancient instruments invented by man, with examples dating back to the 5th millennium B.C.  Its operation can be traced back to the principle of leverage: it consists of a yoke that can swing around a fulcrum, bearing two plates at the ends. Weighing is performed by comparing known mass sample weights with the object of unknown mass. The displacements from the equilibrium position are indicated by the index on a graduated scale. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>IT &#8211; La\u00a0bilancia analitica\u00a0a bracci uguali \u00e8 uno strumento di misura della massa, con un elevato grado di precisione.
