e.Reaction of a tree

2.Loads on trees (allowance 2/2)
 
a.Vertical and horizontal loads
b.Internal and external loads
c.Dynamic vs. static loads
d.Wind loads
e.Tree weight
f.Added mass
g.Growth stresses

3.Geometry of a tree (allowance 2/2)
 
a.Organs - roots, stem branches
b.Big growth period - growth dynamics
c.Quantity vs. quality of material distribution
d.Defects and changes of stress flow
e.Energy dissipation
f.Beams and shells - basic concepts

4.The Material (allowance 4/3)
 
a.Wood structure
b.Functional anatomy of wood
c.Xylogenesis, wood modification, reaction wood

5.Tree Evaluation (allowance 14/7)
 
a.Risk and Hazard in arborculture
b.Tree vitality - physiological view
