Pagina 378 - STONES.* A STRUCTURE may yield, under the pressures to which it is subjected, either by the slipping of certain of its surfaces of contact upon one another, or by their turning over upon the edges of one another ; and these two conditions involve the whole question of its stability.
Pagina 396 - SI. per ton ; and in 1831 it was 51. to 6/. per ton. Thus, this material has gradually come into the domain of applications in construction, from which its high price had long excluded the consideration of its qualifications. Roofs of great span began to be formed of combinations of cast and malleable iron. The eligibility of the one to resist strains of compression, and of the other to resist tensile strains, became familiar to those engaged in practical construction.
