• UNESCO

• Environmental Protection Agency

What is mainly considered in tree cultivation in biomechanics?

• The possibility of tree collapse

• The growth rate of trees

• The water absorption of trees

• The efficiency of photosynthesis in trees

What happens when the load exceeds the carrying capacity?

• Trees will grow faster

• Trees will absorb more water

• Trees will malfunction

• Trees will undergo photosynthesis

In the process of converting force and torque into stress, what needs to be divided by?

• Number of leaves on a tree

• Age of the tree

• Cross-sectional area

• Height of the tree

If the stress on the trunk and branches is the same, what is the likelihood of them failing?

• Both have the same likelihood

• The branches are more likely

• The trunk is more likely

• It is indeterminable

The carrying capacity of a tree is unrelated to which factor?

• The color of the tree

• The strength of the tree's wood

• The shape of the tree

• The diameter of the tree

How does the load-bearing capacity change if the diameter of a trunk is tripled?

• Increases by 3 times

• Increases by 27 times

• Increases by 9 times

• Remains unchanged

The strength of wood is related to what factor?

• The age of the tree

• The growth conditions of the tree

• The color of the tree

• The location of the tree
