Oct 16, 2009. Objective • • To study the bending or flexural behavior of the beam To determine the Modulus of Elasticity and Modulus of Rupture of the wood.
The modulus of elasticity (E) measures the amount a piece of lumber will. for Beams & Stringers and Dimension Lumber, and depth-effect adjustments are.
A statically determinate beam, bending (sagging) under an evenly distributed load.. beams are typically made of steel, reinforced concrete, wood, composites . A stiffer beam (high modulus of elasticity and high second moment of area).
beam as shown in Figure 5, tends to compress the wood at its surface.. The modulus of elasticity is a measure of stiffness and is computed on the basis.

Determination of Strength Properties.

This transformation is based on the ratio of the elastic moduli for the two materials , termed the modular ratio n. M8.19 Composite wood-steel beam. 7.25 in.
