The primary purpose of this Handbook is to provide a source of statistically based design values for commonly used metallic materials and joints. Additionally, other mechanical and physical properties needed for the design of aerospace structures are included.

This chapter, while comprising three major parts, primarily is concerned with joint allowables. Part 8.1 is concerned with mechanically fastened joints; Part 8.2, with metallurgical joints (various welding and brazing processes). Part 8.3 contains information for structural component data; it is concerned with bearings, pulleys, and cables.
