Elastic modulus of section about Y-Y axis.
Z_x 2 A_c Y_c Rightarrow. Z_x A_c Y_c A_t Y_t Rightarrow. We can write the expression for Modulus of Elasticity using the above equation as E FL A δL So we can define modulus of Elasticity as the ratio of normal stress to longitudinal strain.
Table 31 Reference Strength and Modulus of. Youngs modulus can be expressed as. Key design formulas that use the elastic modulus assuming straight rectangular cantilever beams.
σ is the Stress and ε denotes strain. The maximum stress in the beam can be calculated. Thickness of flange or Wall thickness.
Now we have which is called Youngs Modulus or the modulus of elasticityYoungs modulus provides the linear relationship between stress and strain. 58 rows Modulus of elasticity or also referred to as Youngs modulus is the ratio of stress to strain. The modulus of elasticity of graded concrete and the controlling specimens are grouped into 3 three different.
The elastic section modulus is defined as S I y where I is the second moment of area or moment of inertia and y is the distance from the neutral axis to any given fiber.

Youngs modulus is the same for any materialyou could take a spoon or a girder.
The new version of Hookes law is. Table 32 Reference Strength and Modulus of Elasticity for Glued Laminated Timber Used Primarily in Axial Loading 14 3 APAEWS. Youngs Modulus - Tensile Modulus Modulus of Elasticity - E.
Z_x frac bh2 4 - b-t_w h_w2 over 4. Simple Span Beams 6 - 40 Continuous Beams 25 - 40 Table 21 Economical Spans for Glued Laminated Timber Framing Systems. For general design the elastic section modulus is used applying up to the yield point for most metals and other common materials.
And is calculated using the formula below. As long as they have the same youngs modulus and you knew their sizes you could predict how much force would cause. This example works from first principle sectional analysis of a steel wide flange section I beam to compute-Elastic Moment and Elastic Section Modulus-Pla.
Compression perpendicular to grain edgewise Ec90edgemean H 430 2400 2400 - 430 430 Modulus of elasticity. The composite beam is analysed on the basic assumption that plane surfaces remain plane during bending within the elastic limit therefore down the full depth of the beam the strain deflection original length is constant ie the deflection is proportional to the distance from the neutral axis of the beam. Elastic modulus of upper flange about Y-Y axis.
In the formula as mentioned above E is termed as Modulus of Elasticity. The modulus of elasticity for concrete is determined from the following formulas. Parallel to grain E0mean A B D G 13800 10000 10500 9600 11700 12300 Modulus of elasticity.

The plastic modulus of an I-section around x axis is calculated like this. Mechanical deformation puts energy into a material. E stress strain σ ε F A dL L 3 where.
The steel has an elastic modulus E S 21010 3 Nmm 2 and the aluminium has an E A 7810 3 Nmm 2. In the SI system the unit of modulus of elasticity is Nm² and the unit of moment of inertia is m4 therefore unit of bending stiffness is given by Bending stiffness E I frac N m 2times m 4Nm. Thickness of gusset plate.
