ЧТО ОЗНАЧАЕТ СЛОВО TORSION BALANCE
Пружина кручения
Торсионная пружина - это пружина, которая работает кручением или скручиванием; то есть гибкий эластичный объект, который сохраняет механическую энергию при ее скручивании. Когда он скручивается, он оказывает силу в противоположном направлении, пропорционально количеству, которое он скручивается. Существует два типа. Торсионный стержень представляет собой прямой стержень из металла или резины, который подвергается скручиванию вокруг своей оси за счет крутящего момента, приложенного к его концам. Более тонкая форма, используемая в чувствительных инструментах, называемая крутильным волокном, состоит из волокна из шелка, стекла или кварца под напряжением, которое скручивается вокруг своей оси. Другой тип, спиральная пружина кручения, представляет собой металлический стержень или проволоку в форме спирали, которая подвергается скручиванию вокруг оси катушки с помощью боковых сил, приложенных к ее концам, более скручивая катушку. Эта терминология может сбивать с толку, потому что на спиральной пружине кручения силы, действующие на провод, фактически являются изгибающими напряжениями, а не крутильными напряжениями.
Значение слова torsion balance в словаре английский языка
Определение торсионного баланса в словаре - это инструмент, используемый для измерения малых сил, особенно электрических или магнитных сил, путем кручения, которое они создают в тонкой проволоке, нитке или стержне.

The torsion balance, which has a rider beam graduated upon the upper edge
from 1/8 to 15 gr and on its lower edge from 0.01-1.0 g, furnishes a very
convenient means of weighing small quantities without having to use small
weights.

This statement is due to J. Thomson*, who showed that in pulling out a spiral
spring of infinitely small inclination the action exercised and the elastic quality
used are the same as in a torsion-balance with the same wire straightened (§
