"tresses in one direction produce not only a deformation along this direction but also transversally, the relation of both being expressed by the so-called Poisson ratio. However, the consideration... is of no great importance for the first, approximate judgement."

“One should become so familiar with the structure as to have the feeling of being, in full vitality and sentiment, part of it and of all its elements. ...it is necessary to achieve a sincere Einfühlung of the process of resistence... through the deformation that is always essentially united with the process of stressing. ...he comprehension of a structure requires intuitive knowledge of the ethology of its resistance and of its constituent materials.”

“Lightweight concrete obtained with special admixtures producing bubbles throughout the mass shows lower resistance, which makes it less suitable for structural purposes; its practical application is limited to smaller structural elements adequately reinforced in which thermal insulation is required.”

“Even children know that drafting rule is easier to bend flat than across the edges; and... they will not be much surprised if told that for the same width of the rule its resistance is proportional to the square of the thickness and the deflection is inversely proportional to the cube of the thickness. Nevertheless some modern designers seem to be unaware... since they require... beams of such slenderness that they resemble springboards...”

“ost of our structures in the past consisted of individual members having relatively small transverse dimensions as compared with their length, and in such members stress analysis is much more simple. ...any modern structures consist of frameworks of this type, and frequently the word "structure" refers specifically to assemblies consisting of linear elements.”

“had shown that it is possible in Spain to create organizations in which there exists a perfect harmony between different professions, between those above and those below; organizations in which everyone is able to live a life of high human rank, as gentlemen, a life of mutual respect and help and of maximum personal dignity.”

“Clay masonry, like concrete, is a "plastic" material that permits the pouring in situ of large monoliths of any shape or form, with certain limitations and by using special methods. Its economical possibilities when used in walls of popular housing, its excellent heat and sound insulation, as well as its aesthetic possibilities, should not be underestimated. Its resistance and durability can be substantially improved by using modern techniques and methods, for example, admixture of small amounts of Portland cement in accordance with granulometric investigation, petrographic composition, and rheological behaviour of all constituents.”
