Saint-Venant's Principle In region of a connection or where load is applied, use of common equations such as cr= PIA can be invalid. The common equations can be valid starting at a distance greater than the largest cross-sectional distance away from the disturbance. p p L "~--C , ~(~ ,!~-b Q-- b-- ~cction (I-a c-- p in .
