JF 05-3b Lever Applications

The document discusses clamping and workholding principles related to lever systems. It provides equations showing how clamping force (P) relates to applied force (F) and lever lengths (L1 and L2) based on lever principles. Diagrams show examples of lever clamps including spherical washers, quick lock knobs, C-washers, and single lock levers. The document is intended to explain lever applications for jigs and fixtures.
