Kinematics of Mechanisms: Velocity Diagrams

  • G. E. Drabble
Part of the Foundations of Engineering book series (FES)


This programme describes a graphical method of analysing mechanical devices, in order to determine the velocities of the various parts. Such analysis might be needed by the designer of a machine tool, who may need to know how the speed of the cutting-tool varies during its stroke, when the driving motor turns at a certain speed. Graphical methods have the disadvantage that they are slow, and not always very accurate. For some simple devices it is possible to determine velocity by calculation, and this is the subject of Programme 4. In recent times, velocity analysis of more complex machines has become possible by the use of computers. But engineers are still required to know the principles of the graphical analysis of machines.
