The philosophy of design — dge, would it be better to use a continuous shell structure made from plates or panels or else a criss-cross lattice arrangement built up from rods or tubes and braced, perhaps, with wires? Again, why do we have so many muscles and tendons and comparatively few bones? Furthermore, how is the enginee

— l branches of science. If an engineering structure breaks, people are likely to get killed, and so engineers do well to investigate the behaviour of structures with circumspection. But, unfortunately, when they come to tell other people about their subject, something goes badly wrong, for they talk

Why structures carry loads — or even to sustain its own weight ? This is, essentially, the problem of ‘Why we don’t fall through the floor’ and the answer is by no means obvious. It lies at the root of the whole study of structures and is intellectually difficult. In the event, it proved too difficult for Galileo, and the cre

The invention of stress and strain — cientists who did study it tried to deal with forces and deflections by considering the structure as a whole — as Hooke had done — rather than by analysing the forces and extensions which could be shown to exist at any given . the material. All through the eighteenth century and well into the ninete

Strain energy and modern fracture mechanics — ion and the magnitude of the stresses in most kinds of structures in a rather broad, generalized or academic way. However, many practical engineers had not long come to terms with calculations of this kind before Inglis planted the seeds of doubt at the back of their minds. Using the elasticians’ ow
