• Introduction
• The position of equilibrium points and the size
  of stick regions are affected by the compressed
  spring
• Increasing the compression ratio and the
  stiffness of the spring can make the system have
  a smaller size of the stick regions.

• 4. Summary
• These multiple equilibrium points can be
  separated far off by increasing the compression
  ratio.
• Increasing the compression ratio and the
  stiffness of the spring reduces the size of stick
  regions significantly
