A can that bulges at one end when the opposite end receives pressure is called a what?

A can that bulges at one end when the opposite end receives pressure is referred to as a "flipper." This term is used to describe a particular physical phenomenon where the can experiences uneven pressure distribution, causing one end to deform or bulge outward.

The term "flipper" indicates that the can essentially 'flips' in response to pressure, highlighting the change in shape that occurs in response to force applied to the opposite end. Understanding how pressure affects can structures is important in fields such as materials science and engineering, as it relates to pressure containment and structural integrity.

Other terms, such as "springer," "sweller," and "tester," do not accurately describe this specific behavior of a can under pressure and are not commonly used in this context. A "springer," for instance, might suggest a mechanism or structure that flexes or returns to its original shape, while "sweller" could imply expansion without the specific directional pressure response seen in a flipper. The term "tester" typically relates to an apparatus that evaluates certain properties or functions rather than describing a physical shape change related to pressure.
