se inrapidity until they die out. The lawsof torsion found in this way bycoloumb are :— 1. The angle of torsion is propor-tional to the force of torsion applied. 2. With same force of torsion, andwith wires of same diameter, theangles of torsion are proportional tothe lengths of the wire. 3. The… … Fig. 51 where K is a constant for each different material; ll\ the angle of torsion ; F, the applied force; /, the length of the wire; r, its diameter. In lead, for instance, K is about equal to zero, very high in all hard metals, phosphor bronze, steel, hard drawn iron, silver, glass, and highest…
