Latham, John Herbert · Cambridge : Macmillan · leaf 217
per space per lattice = 1.5 tonsapproximately. That on the bottom boom = .55 tons approximately. Hence, first, the difference of the strain of two bars 15spaces apart, under full load = 1.5 x ^2. And consequently the difference of the strain of twoconsecutive bars = 1.5x^2-^15 = ^^2. Hence, also,…
