DescriptionAn idealized theoretical equation to calculate flexural stiffness using transverse vibration of a simply end-supported beam is being considered by the American Society of Testing and Materials (ASTM) Wood Committee D07 to determine lumber modulus of elasticity. This commentary provides the user a quantitative view of six factors that affect the accuracy of using the idealized theoretical equation, idealized assumptions, and idealized boundary conditions. The six factors that affect the calculation of the flexural modulus of elasticity are ranked in order of importance, and recommendations are given. Not covered are the precision and accuracy of the physical measurements.
