Let A F and R X be the radii of curvature at the points A and R, then the triangles A a b and A a F, as also E s r and R r X , are similar; and therefore, since A a = R r, we have rs : E r : : R r : E X a&:Aa::Aa:AF; therefore r s : a b : : A F : R X ; but r s : a b : : C L : C G, and consequently, C L : C G : : A F : R X ; whence again, C L .

In order now to trace the property of the curve, let C L = x, R L = y, and R C = z; then, as is shown by writers on the diffe­ rential calculus, the radius of curvature 2 dz* d x ,d R X = 2 2 (d x + d y ) | —dx .

Hence, if the length of the beam be I, and the number of equal weights m, and the sum of all the weights W , then the above becomes , / = ' " rW m 2 / o + \ l m + 2 1 3 Z „ \ml\ — + — + &c. m m m / W x — ; or, m Z W / = — x (1 + 2 + 3 + 4, &c. 4 m) ; or, m ( | m + 1) \ m _ j I W m + j Z W m _ 2 ~ 2m * ' 2 X 2 - W + Z_W 4 m' Hence, when the weight is uniformly distributed through the whole length, the number of points of suspension, m, becoming infinite, the last term of the preceding expression, and there results vanishes; / = \ IW, for the strain on the centre of a beam, when the weight W is uniformly distributed throughout its length; which is half what it would be if it were all suspended from its middle point.

Strain; that is, as I W : therefore, again, the deflection varies as 3 3 I W I w -g—; or, denoting the deflection m D by 6, we have - y y = E, a constant quantity, the same result as before. 4 9 . The same may be otherwise demonstrated as follows : In the above investigation it is shown that D m, which is sup­ posed to represent the deflection, is expressed by the equation ^ 2 _ \ ra =*It m + 1 + t t and that in any other beam of which the number of parts are m', the deflection is also from which we conclude, that when m is infinite, the deflections are as 2 2 dm 2 2 : cZ'm' ; or as eZ Z : d' Z ' ; where Z and V denote the two lengths.
