The phrase "a box section" is correct and usable in written English.
It can be used to describe a specific type of structural element or component that has a box-like shape, often in engineering or construction contexts.
Example: "The engineer recommended using a box section for the support beams to ensure maximum strength and stability."
Alternatives: "a rectangular section" or "a square section".
All three models had semi-circular ends, separated by a box section for the 2 longer models.
Since the strength and stiffness of a beam are proportional respectively to the square and cube of its depth, while both the torsional stress and stiffness of a box section are proportional to the area enclosed by it, it follows that the strength and stiffness of a body shell are potentially much greater than of a chassis frame.
This is due to the high flexural and torsional stiffnesses of SWs, forming a box section.
Indeed, this is mainly due to the fact that in type-1, the four SWs form a box section and beam elements represent individual elements and not a box section.
Indeed, this is mainly due to the fact that in type-1, the four SWs form a box section and that beam elements represent individual elements and not a box section.
This is due to the fact that the SWs in type-1 constitute a box section, which has very high flexural and torsional stiffnesses.
At the bottom of the form, there is a boxed section, with the bold headline "Authorization: Please read carefully, initial each paragraph and sign below".
Further, a series of experiments of a box-section steel beam are designed and fabricated in laboratory.
The air passes along a box-section horizontal tube bundle filled with paraffin wax (phase change material).
The PA type utilized an open-section layout for the node, whereas the PB type utilized a box-section layout for the node.
It has a box-section steel spaceframe and it has steel armour plating that can protect the occupants from bullets and bombs.
