Also known as a torsion scale. A type of balance that utilizes the fact that the torsion angle of a straight spring is proportional to the force applied. An object is suspended from a thin wire made of metal or fused quartz, a couple force is applied to it, and the couple moment is measured from the angle of torsion. It is suitable for measuring weak forces. → Related topics Coulomb | Coulomb's law | Torsion | Scales | Gravitational constant Source : Heibonsha Encyclopedia About MyPedia Information |
ねじりばかり(秤)とも。てんびん(天秤)の一種で,直線ばねのねじれ角が加えた力に比例することを利用したもの。物体を金属または溶融石英の細い線でつるし,これに偶力を加え,ねじれの角から偶力のモーメントを測定する。微弱な力の測定に適している。 →関連項目クーロン|クーロンの法則|ねじれ|はかり(秤)|万有引力定数 出典 株式会社平凡社百科事典マイペディアについて 情報 |
