what is the weight a balsa wood structure can support before failing?

Question

this is wood-working

Answer 1

This depends upon the grain and quality of the wood, the type of structure and the methods of construction.

Balsa wood has been used to make surfboards. These can take the pounding of the water and hold the weight of a human over an 8 foot span without breaking.

I have made three foot tall towers out of balsa wood what could support my own weight.
