Opis

The most difficult problem most mechanical designers face at the conceptual design phase is the creation of design alternatives. Mechanism Design: Enumeration of Kinematic Structures According to Function introduces a methodology for systematic enumeration and classification of mechanisms that is not available in any other resource. It also provides numerous atlases of mechanisms that can be used by engineers as a source of ideas for mechanism and machine design. OTI 1
