  1. Problem №1 Adhesive tape Made by: SapeginVitaliy Team of Russia

  2. Terms of the problem • Determine the force necessary to remove a piece of adhesive tape from a horizontal surface. Investigate the influence of relevant parameters.

  3. Plan

  4. Parameters 1) surface square 2)angle of force application 3) initial pressure

  5. Setup Body which is removed from tape Basket with the weight Adhesive tape. sticky side up

  6. Dependence on pressure Pressing bars Adhesive tape. sticky side up

  7. Dependence the removing force on the initial pressure

  8. Explanation

  9. Dependence the removing force on the area of surface

  10. Force necessary to remove 1mm² area. Force necessary to remove 1mm² area of tape

  11. Dependence on removal angle

  12. Dependence the removing force on the application angle

  13. Dependence the vertical part of removing force on the application angle

  14. Derivation of the formula working area tape

  15. Maximal distance

  16. Dependence the working area on the cotangent of application angle

  17. Scheme Adhesive tape Working glue

  18. Results and conclusion: • The force increases while the initial pressure rises until the force becomes saturated. In this case, it will remain constant • The force increases linearly while the area increases • The force required to remove the tape increases while the angle decreases • Tape has the working area • Maximal distance between tape and surface found
