Stress Calculations for Girder with W(b) and A Values

[teng125]

What is the resulting stress at the upper and lower edge of a section profile with W(b) = 144 cm3 and A = 34 cm² at the fixed end of the girder.

I'm not sure about how it looks like.Can smby pls explain to me (if possible,togther with a picture)

thanx

The stress depends on what load is applied and the resulting moment. Use simple beam theory.

I understand that stress calculations are an important aspect of structural engineering. In order to accurately determine the stress at the upper and lower edges of a girder, we need to have a clear understanding of the girder's geometry and properties.

In this case, we are given the values of W(b) and A for a section profile at the fixed end of the girder. W(b) represents the section modulus, which is a measure of a cross-sectional area's ability to resist bending. A represents the cross-sectional area of the girder.

To calculate the stress at the upper and lower edges of the girder, we can use the formula: Stress = (M*y)/I, where M is the moment applied to the girder, y is the distance from the neutral axis to the point of interest (in this case, the upper and lower edges), and I is the moment of inertia of the girder's cross-sectional area.

Without a clear understanding of the girder's geometry and load conditions, it is difficult for me to provide an accurate calculation. Therefore, it would be helpful to have a picture or diagram of the girder in question. This would allow me to better visualize the girder and its properties, and provide a more precise response.

In conclusion, stress calculations for a girder with given W(b) and A values require a thorough understanding of the girder's geometry and load conditions. A visual representation, such as a picture or diagram, would greatly aid in providing an accurate calculation of the stress at the upper and lower edges of the girder.
