The phrase "a cross section which is" is correct and usable in written English.
It can be used when describing a specific part or aspect of a larger whole, often in contexts like analysis, research, or technical descriptions.
Example: "The study provided a cross section which is representative of the entire population, allowing for accurate conclusions to be drawn."
Alternatives: "a segment that is" or "a portion that is".
We consider the Saint-Venant torsion of a cylindrical rod of a circular cross section which is filled up by an assemblage of composite circular cylinders.
The flexoelectric energy harvester works even for a single layer beam with a symmetric cross section which is not possible in piezoelectric energy harvesting.
This paper newly proposes a semi-empirical calculation for design of electrostatically driven flexural mode silicon (Si) mechanical resonators with a variable cross section which is applicable to a feasibility study of their development without finite element analysis (FEA).
Computational fluid dynamics (CFD) methods, based on Cartesian or cylindrical coordinate systems, have certain limitations regarding irregular geometries[9], such as the geometry of a jet cross section, which is connected to a channel.
The mask utilizes an airway tube with an elliptical cross section, which is intended to facilitate placement without requiring the insertion of fingers into the mouth.
The shaft is straight, with a nearly rectangular cross section which is ventrally concave and dorsally carries a smooth peak.
The tungsten coating has a hardness of Hv = 260 300 along its cross section, which is a little lower than the hardness usually quoted for pure tungsten.
The test article is composed of a suitable copper-alloy block warmed up by cartridge heaters and of a single channel with rectangular cross section, which is fed with transcritical methane flow.
We also find a muted response in the municipal cross section, which is not our preferred model but we include to provide comparison with previous literature.
In addition, the absorption cross section, which is a determining factor for the power of the energy converter system, is enhanced by the larger local concentration of the RC (i.e. by the larger chromophore density).
