Introductory paragraphs: The design fundamentals for structural components in machinery systems have been discussed in the previous twelve chapters. This chapter discusses the design of a simple machine, a floor crane, shown schematically in Figure 13.1. The design of this machine uses the information on combined loadings discussed in the previous three chapters and information from earlier chapters, such as bearing stresses and plug shear. The column and the lift arm are subjected to axial tension and compression loads combined with bending. The base members experience torsion and bending loads and form a plane grid. The brackets, side plates, and some of the members are attached using fillet welds. The Law of Cosines is used to obtain the coordinates for the lift arm and to determine the location of the lower bracket. (Download PDF) (Export to EndNotes)
