受力與彈簧伸長量成正比。庫侖扭秤:懸絲的扭力能夠為物理學家提供一種地測量很小的力的。扭轉力矩與懸絲的扭轉角成正比,與懸絲直徑的4次方成正比,與懸絲的長度成反比。庫侖扭秤的主要部分是一根金屬細絲,上端固定,下端懸有物體,在外力作用下物體轉動,使金屬絲發(fā)生扭轉,測量出扭轉角度,就可以根據(jù)扭轉定律算出外力。磅秤:磅秤的原理是依據(jù)力來測的,但是在地球上,在認為地球是不動的參考系(慣性參考系)中,磅秤稱出來的結果是“正確”的。因為這時重力加速度是取了9.8N/kg的。要是到了月球上,稱出來的就不是“正確”的了,因為磅秤把重力加速度還看作是9.8N/kg,而事實上月球上的重力加速度比這小多了。定律彈簧秤:主要是胡克定理:F=k△x.彈簧的長度與所受外力成正比。由此看來,奧耶領的發(fā)明權了上的確認。在很長時期里,天平制造業(yè)中流行一種理論,認為天平的橫梁越長天平越靈敏。但是有一個叫波爾·邦格的人卻不受這種理論的,1866年,他設計、制造了一架短橫梁分析天平。后來,在天平設計理論方面,他也有建樹。下圖所示的就是1866年邦格制造的早的一臺短梁天平。羅馬時代晚期的錢幣天平羅馬時代晚期的錢幣天平天平的改進,除了橫梁、點、游碼、刻度等方面以外,還在其它方面,例如,19世紀前半期,已經出現(xiàn)了旋鈕天平。旋鈕天平有什么優(yōu)點呢?原來,早期的天平,橫梁架在的柱上,用時和不用時都是一樣的。后來分析天平出現(xiàn)了,分析天平的刀口用瑪瑙制成,為了刀口的損傷,不用天平時。
