The modulus of elasticity for Basswood and Balsa wood under compression is definitively established in the Wood Handbook. Basswood exhibits a compressive strength of 15,300 kPa and a bending elastic modulus of 1040 ksi (7,200 MPa) when measured parallel to the grain at 12% moisture content. In contrast, Balsa wood shows a compressive strength of 14,900 kPa (2160 psi) and a bending elastic modulus of 490 ksi (3,400 MPa) under the same conditions. The discussion highlights the importance of differentiating between compressive and bending tests in wood data.
