ABSTRACT
This chapter is concerned with mainly stress distribution in this group of miscellaneous machine components. Consideration is given to thermal stresses, the material strength, and an appropriate theory of failure to obtain a safe and reliable design. A composite or compound cylinder is made by shrink or press fitting an outer cylinder on an inner cylinder. A unique class of composites, formed by wrapping of high-strength filaments over a mandrel, followed by impregnation of the windings with a plastic binder and removal of the mandrel in pieces, is called filament-wound cylinders. Heavy disks often serve as flywheels designed to store energy to maintain reasonably constant speed in a machine in spite of variations in input and output power. In single or tandem configuration, they form the pressure-carrying structure and living space in most deep-submergence oceanographic vehicles.
