The modulus of elasticity (MOE, E) of wood is most commonly used in the calculation of deflections (sag) of wood beams. By `beams’ I include joists, rafters, girders, decking boards, any … wood used structurally to support loads across spans …
When we examine deflections of wood members (beams, joists, rafters, girders, etc.) we generally look at two kinds, actually three … the deflection due to the `live load’, e.g., people walking on a floor, wind on a wall, and so …
