amounts,S and t, p where /* is by definition Poissons ratio. 1152 APPENDIX XI. Now let a unit cube be subjected to the pressure 3 P in thedirection of its length ; and let equal and opposite pressures± P be applied to each of its sides. We shall then have auniform pressure, P, on each surface,… … ■t^m. to diminish the length. Hence we have, adding the threeeffects upon the length together, V We have also, remembering that the total longitudinal pres-sure is 3P, PROOFS. 1153 ^ = 3X J; hence, equating the two values of V, and dividing through by3P, J- = J- + -L.. (1) By means of this equation…
