To quickly assess the difficulty of the text, read a short excerpt:
Then the direction of the earth-pressure is GJ; and if ^l^is made perpendicular to AB and equal to HF, E = yAABK, and the triangle gives the distribu- tion of the pressure. The point of application is found by drawing through the centre of gravity of the triangle a perpendicular to AB. 40 TEEOBT OF THE BETAININQ -WALL. The proof of this construction is as follows : Conceive HD drawn, and its intersection with GJ io be at L. Then from the notation of Pig. 3, where s= ip, FD — AD cos tp, HD— 2 AD... cos {^- a). Since, now, cos ('ia — is perpendicular io AB, the earth-pressure has the direction GJ. Further, n-m_ FD sin or _ sin « cos 9> ~ sin (a -f = ^ '-, or, with reference to the value of FD.
