On the mechanics of balsa and other woods
WebI'm building a bridge out of balsa-wood strips for school, and wanted some advice. These are the specifications: Height: 2 to 6 in; Length: 12 inches, plus 1-3 inches on each side resting on tables; Width: 2 +- 1/16 in at the base; Weight: <= 50 g; The objective is maximum efficiency (load it can hold divided by weight), not just load. WebBalsa wood is one of the preferred core materials in structural sandwich panels, in applications ranging from wind turbine blades to boats and aircraft. Here, we investigate the mechanical behavior of balsa as a function of density, which varies from roughly 60 to 380 kg/m3. In axial compression, bending, and torsion, the elastic modulus and ...
