例句與造句

1. There are two types of section moduli, the elastic section modulus ( S ) and the plastic section modulus ( Z ).
2. The elastic section modulus is defined as Z = 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 fibre.
3. He correctly assumed a central neutral axis and linear stress distribution from tensile at the top face to equal and opposite compression at the bottom, thus deriving a correct elastic section modulus of the cross sectional area times the section depth divided by six.
4. It is also often used to determine the yield moment ( M y ) such that M y = S ?? y, where ? y is the yield strength of the material . Elastic Section Modulus can also be defined as the first moment of area.
5. In the case of T-sections if there are tensile fibres at the bottom of the T they may still be more critical than the compressive fibres at the top due to a generally much larger distance from the neutral axis so despite having a higher allowable the elastic section modulus is also lower.
6. It's difficult to find elastic section modulus in a sentence. 用elastic section modulus造句挺難的
7. For a conservative ( safe ) design, civil structural engineers are often concerned with the combination of the highest load ( tensile or compressive ) and lowest elastic section modulus for a given section station along a beam, although if the loading is well understood one can take advantage of different section modulus for tension and compression to get more out of the design.
8. The two terms are related by the yield strength of the material in question, F y, by M p = f y * S . "'Plastic section modulus "'and "'elastic section modulus "'are related by "'shape factor "'which can be denoted by'k', used for an indication of capacity beyond elastic limit of material.
