Kinematics of Mechanisms: Acceleration Diagrams
In this programme, we continue with the analysis of mechanisms, begun in Programme 2, extending the graphical technique to include acceleration. To a design engineer, acceleration is more important than velocity, as it is directly related to force. Much modern machinery operates at very high speeds; the ordinary automobile engine is a typical example, and the moving parts undergo accelerations of a very high order. If such machinery is to operate without breaking apart due to internal stresses, the designer must be able to predict the inertial forces accurately, and allow for them.
