Abstract: THE use of influence lines for the determination of maximum moments and criterions for wheel loads is presented in many modern text books.The object of these few pages is to bring attention to the fact that for loads on all ordinary trusses, the influence ^ , J^ diagrams for bending moments are drawn by following a single simple rule, and that the diagrams so constructed require no computations for their direct application.In addition to this the influence diagrams for loads on continuous trusses, cantilever trusses and arches are shown to be based upon the one general diagram for simple trusses.While the diagrams, as a rule, are constructed for moments yet they can be as easily drawn for stresses or even areas of truss members.The use of the influence diagrams in the determination of criterions for the positions of wheel loads which produce maximums is explained and shown to be very simple.
