haft a must, conse-quently, be eight times as strong as shaft b, in resisting tor-sional stress. Thus, the strength of a solid shaft /%%%ffi%^ Fig. 38.increases as the cube of the diameter.Shaft a is twice as large in diameteras shaft b, and is, therefore, eight timesas strong as b, because 23 = 8.… … 268 STRENGTH OF MATERIALS. Therefore, if the constant corresponding to a load, which,applied to an arm one foot long will twist off or destroy a barone inch in diameter, is found, the breaking load for any roundshaft of the same material when under torsional stress may beeasily calculated. The…
