If, therefore. Pi be the ultimate strength ofa bar of cross section S to resist shearing in n places, andif /, be the ultimate strength of the material, we havethe expression— 1 Pi = mS/.. The assumption on which this equation is founded isnot strictly correct; indeed, the actual shearing describeddees not correspond with any simple homogensous stress,and the form of the cross section shorn through must exer-cise considerable influence on the strength of the piece toresist shearing. In a round pin the maximum intensityof shearing stress is | of the mean intensity, and in a rect- STRENGTH OF MATERIALS.!. B K I D G E S 28
