• ISA Florida Chapter and the Tree Fund

What is the main consideration of biomechanics in tree cultivation?

• Water absorption of trees

• Disease prevention in trees

• Possibility of tree collapse

• Growth rate of trees

What happens when the load exceeds the carrying capacity?

• Trees wither

• Trees grow faster

• Trees bloom

• Breakdown

What are force and moment components of?

• Strength

• Stress

• Bearing capacity

• Load

How is stress calculated?

• Divide the load by the cross-sectional area

• Multiply force by bending moment

• Multiply the load by the cross-sectional area

• Divide the bending moment by force

What is the first factor affecting the carrying capacity of a tree?

• The shape of the tree

• The age of the tree

• The diameter of the tree

• The height of the tree

The relationship between a tree's carrying capacity and its diameter is?

• Related to the square of the diameter

• Related to the cube of the diameter

• Inversely proportional

• Directly proportional

The variation in wood strength is mainly due to what?

• The color of the tree

• The species of the tree and growth conditions

• The location of the tree

• The age of the tree

If the diameter of a tree is tripled, how will its carrying capacity change?

• Tripled

• Remains unchanged

• Increased ninefold

• Increased twenty-sevenfold

One way to reduce the possibility of tree failure is what?

• Reduce the area of the canopy

• Increase the diameter of the tree

• Increase the age of the tree

• Increase the height of the tree
