ABSTRACT
In this chapter, a number of procedures gathered in units LibMecIn and LibMec2D available with the book are presented as a preamble to Chapter 6 where the kinematic analysis of planar linkage mechanisms using Assur groups is discussed. Some of these procedures are also used in the synthesis and analysis of cam-follower mechanisms, the subject of Chapter 7. ¬ey allow for automatic graphical representation and animation of rotary and linear motors, of oŠset points and complex shapes attached to mobile links, and for visualizing the velocity and acceleration vectors and of loci of moving points. Procedure Spring used in the elastic pendulum example in Chapter 3 is also available from unit LibMec2D. At the end of the chapter, two approaches to generating mechanical system simulations accompanied by dynamic plots with scan lines and scan points will be discussed, one using the procedures in unit LibPlots and the other using the D_2D program.
