Before I attempt to help you on this scene, you need to respond to scripting help needed.

i have replied to your comment

See response scene.

What was done:
  Turn off clouds.
  Turn off gravity.
  Read entire article.
  Set motorTorque for all axles to +inf.
  Add mechanism to pull lowest link.
  Select all links and turn off all collision layers.
  Set bendConstant for thinner sections to 10.
  Set sim.frequency to 240.
  Set air multiplyer to 100 (for damping).
  Add code to puller hinge to track force and deflection.
  Add display box to show force and deflection.
  Add circle to track force and deflection.
  Add plot to track circle.
  
What still needs to be done:
  Tune each of the (3) mechanisms individually by adjusting the bendConstants so that the force deflection curves look like those in the research article.
  Modify the bendConstants in the assembly to the tuned values from the previous step.
