36+ Section Modulus Equation Pictures

36+ Section Modulus Equation Pictures. (this parameter is sometimes called the moment of inertia , but as there are other applications of this term in physics, it is best to. For a beam which has been bent, the maximum stress σmax will occur at the maximum distance ymax from the neutral axis.

The section modulus equation for an elastic object is given by z = i / y , where y is the distance described above and i is the second moment of area of the section. Correlation section modulus < > area moment of inertia. Thus section modulus isn't actually new information, but it's convenient from a design perspective because it groups together all the dimensions of the beam cross section into one term.

For materials with equal tensile and compressive yield stresses, this leads to the division of the section into two equal areas

More lessons for a level maths. Dividing this equation by tensile strain, we obtain the expression for young's modulus: The constant, c1, depends on the length, and the block coefficient, cb. Elastic section modulus for shear connections.
