A dynamic (flexible) cabling system differs from a static system primarily in that it:
Answer: Allows limited movement to encourage trunk taper and strength
Dynamic systems use flexible materials that permit some branch movement, stimulating natural wood strengthening through stress response while still limiting extreme deflection.
Which ANSI standard governs cabling, bracing, and support systems for trees?
Answer: ANSI A300 Part 3
ANSI A300 Part 3 specifically covers supplemental support systems including cabling, bracing, guying, and propping.
When a tree is guyed to the ground after transplanting, the guy wires should be removed:
Answer: Once the tree has established sufficient root anchorage, typically one to three growing seasons
Guys should be removed once the tree has enough root anchorage to stand independently, typically after one to three growing seasons, to prevent girdling and allow normal taper development.
The 'target analysis' in cabling and bracing assessments refers to:
Answer: Identifying what or who could be harmed if the tree fails
Target analysis identifies the people, structures, or values at risk below a tree, which is essential for prioritizing supplemental support decisions.
What type of hardware allows post-installation tensioning of a static cable?
Answer: Turnbuckle
Turnbuckles are threaded devices inserted in the cable that can be rotated to increase or decrease cable tension after installation.
What is a key disadvantage of installing a brace rod too close to an existing crack?
Answer: It may split the wood further if placed at the crack's edge
Placing a rod too close to a crack can act as a wedge, extending the fracture rather than stabilizing it when the rod is tightened.
Which factor most influences the diameter of cable selected for a cabling system?
Answer: The diameter and weight of the limbs being supported
Cable diameter is primarily determined by the mass and leverage of the limbs it must support, ensuring the cable's rated load exceeds the expected forces.
