40 LATERAL PRESSURE, ITS AMOUNT. _ [{cu. 1v. And the other values of —2— are for the several shells, tan gr | — 0°826756, + 0°139920, + 0°654135, + 0°917944. Hence calculating the value of sin’ ga — ga sin ga cos ga, equation (1) becomes y =< rt — 0°62499 goin’ qr (1 _ “4 T. . .¢ _ gr \. er It is easily seen that sin‘ gr (1 tan a? a) is of four dimensions in 7, so that the second term vanishes when r= 0. Moreover, between the values of gr = ga and gr = py ener increases from — 3°035906 to 0, and continues to increase from 0 to 1 when gr=0; so that between those limits 1— qr tan gr decreases from 4°035906 to 0. It appears then that a de- creases from 1 at the surface to 0 at the centre. And if we give to r the values r=, then y=0. r = 4a, y=— 064557’. r = a, y=— 0°7997 7’. r= a, y= 015737’ r=ta, y= 3'5689 T. r=, : y=. So that the curve representing the values of y from r = 0 to r= a will be of the subjoined form, having the axis of y for an asymptote. commiclsoolkks (CO)
