This article presents a recall of an article "A preliminary study of the transverse strength of structural bamboo," originally written by A.L. Teodoro in 1925. The author did bending tests on bamboo with a clever machine. He used the following variables: first two species, Bambusa spinosa and Bambusa vulgaris; second three curing periods: 30, 60 and 90 days; third two curing conditions: sun or shade; fourth two seasons: wet or dry. The results of all tests show that more force is needed to break transversely a large and thick pole than a small thin one, that is, when the poles were cured under the same conditions. They also seem to show that the time of curing must be shorter in the dry season to obtain the best result in transverse strength.
