), in order to balance it, the forceexerted being always proportional to the angle of torsion. Amodification of the torsion-balance was employed by Cavendish,and subsequently by Bayly, in the determination of the densityof the earth. (107.) Limit of Elasticity. — It has been several times stated in… … Fig. 202. 194 CHEMICAL PHYSICS. limits, all solids were perfectly elastic. The phenomena of elas-ticity may be developed by torsion in those substances which seemthe most destitute of tliis property. Thus, if we take a leadenwire two millimetres in diameter and three metres long, fix oneend of it…
