lkthread or wire is tied aroundthe solid and a loop made ofthe end several inches awayfrom the solid, so that thewhole may be freely suspended from the arm of the bal-ance (Fig. 56). The weight is then taken in air. Letthis be represented by x. A glass of water is now broughtunder the solid and… … Fig. 56.—Specific-gravity balance. 100 PHYSICS Then x — y will represent the loss of weight in water, and we will have -r. •, x specific gravity = y Example.—A piece of limestone rock. Weight in air = 17.65 Weight in water = 10.99 Loss of weight in water = 6.66 Specific gravity = l^ = 2.65. That is…
