This chapter discusses joints with rotary or linear motion, mostly with sliding or rolling friction. It is, however, convenient to start with a short section on flexure bearings, useful where small movements are involved. In instrument work, crossed-leaf springs form a friction-free and slack-free pivot for angular movements of a few degrees. The arrangement requires at least three springs for symmetry. Any loads which tend to compress the springs must be kept small to avoid buckling.
