Introduction

A planar four bar linkage.

Geometry

To define this planar mechanism we only have to fix the length of the bars:

	1.25
	1.25
	1.25
	1.25

These constant values can be easily changed in the formulation.

Process

This example is treated following this steps (from the main CuikSuite folder):

• Generate the equations:
  • bin/cuikequations examples/FourBars/FourBars
• Solve the positional analysis problem:
  • bin/cuik examples/FourBars/FourBars
• Plot and visualize the configuration space:
  • bin/cuikplot3d examples/FourBars/FourBars 3 7 15 0 fb.gcl
  • geomview fb.gcl
• Visualze the configurations:
  • bin/cuiksort examples/FourBars/FourBars
  • scripts/cuikplayer examples/FourBars/FourBars examples/FourBars/FourBars_1

For more detailed instructions please, see the particular formulation.
