Historical Sketch.*—For two hundred and fifty years the true theory of the strength of a beamhas been a much-mooted question amongst physicists, engineers, and mathematicians. Galileo was the first of whom we have any record who undertook to discuss the problem. In hisfamous… … Fig. 164. tension which acted about the base of the beam as a fulcrum. On this theory the moment of resistance of a solid rectangular beam would be where /is the ultimate strength of the material in tension. Robert Hooke first published his famous law of the relation between strain and stress in…
