nd let I be theincrease of length in the direction of the pull and the decrease of length in the direc-tion of the push. It is convenient to express I as a fraction of L, and we will repre-sent this fraction by the letter a( = lf L). It is important to know that the angleof shear 0 as above defined… … Fig. 102. Fig. 103. angle 0/2 is very small and it is therefore sensibly equal to gh divided by gn.That is, 0/2 is equal to l/L( = a) so that 0 = 2a. 104. Slide modulus of a substance. The angle of shear <f> produced in Fig. 99by the shearing stress S is proportional to S, according to Hookes…
