Fork Reading

Welcome back to another of my ‘Fork Talks’! Today, I’ll be sharing my research progress, covering various experiments and their outcomes, including an examination of the physical properties of forks in trees. We'll explore planned studies on electronic forks, measuring oscillations in bifurcations, and the significance of bark inclusions. My aim is to simplify our findings for tree surveyors, aiding in the evaluation of tree stability. Join me as we dive into the science behind tree fork analysis and prepare for exciting future experiments!

  1. Fork Reading Duncan Slater MICFor

  2. Yet another of my ‘Fork Talks’ Thank you for having me back!  Again!! Today, I want to report my research progress So here comes the ‘sciency bit’…

  3. Presentation Summary • Experiments and their outcomes • Planned experimental programme • Reading forks • Your tea! 

  4. Experiment Oneaka « Genghis Khan »

  5. Experiment OneOutcome No. 1

  6. Experiment OneOutcome No. 2

  7. Experiment OneOutcome No. 2

  8. Experiment OneOutcome No. 2

  9. Experiment OneOutcome No. 3

  10. Experiment Twoaka « Driller Killer »

  11. Experiment TwoOutcome No. 1

  12. Experiment TwoOutcome No. 2 Forkwood was 17.5% denser than stemwood in hazel

  13. Experiment Threeaka « X-Ray Vision »

  14. Experiment ThreeOutcome 1:

  15. Experiment ThreeOutcome 1

  16. Experiment ThreeOutcome 2

  17. Experiment Fouraka « Bristol City »

  18. Experiment FourMethodology

  19. Experiment FourOutcome The forks of modern clones were significantly weaker due to their V shape

  20. Experiment Fiveaka « FEA – Forking Electronic Answer »

  21. Experiment FiveExpected outcome Stronger Weaker

  22. Experiment Sixaka « Bark worse than Bite»

  23. Experiment SixExpected outcome Forks with bark inclusions vary in strength, and are not necessarily a flaw Stronger Weaker

  24. Planned Experimental Programme • Constructing a 3D “electronic fork” (FEA) • Measuring oscillations of bifurcations in the wind with laser sensors • Testing the effects of bracing and cracking • Investigating environmental factors that affect the development of bark inclusions • Measuring the pre-strains found at forks • Testing the ‘Axiom of Uniform Stress’ in relation to fork oscillations using strain gauges

  25. Reading Forks Although the topic is complex, I hope to be able to simplify the findings for the end-users: tree surveyors It is likely through examining the fork’s morphology and position, an educated judgement could be made on its risk of failure

  26. Remodelling

  27. The Write-Up! • First paper in Arb Journal, 2010 • Two submitted to journals currently • Two more submissions by end of 2012 • Overall target is 12 papers from PhD

  28. Acknowledgments • Dr. Roland Ennos – supervisor • Myerscough College – sponsor • Dr. Robert Bradley – MXIF • Mike Carswell – supplier of hazel forks • BSc (Hons) students: Joe Barnes, Mat Dumelow, Claire Harbinson, Sam Turner and Ian Williams

  29. Your tea ! On time, as promised! 
