The test method for conducting the test usually involves a specified test fixture on a universal testing machine. Details of the test preparation, conditioning, and conduct affect the test results. The sample is placed on two supporting pins a set distance apart and two loading pins placed at an equal distance around the center.
[2] A disadvantage of air bending is that, because the sheet does not stay in full contact with the dies, it is not as precise as some other methods, and stroke depth must be kept very accurate. Variations in the thickness of the material and wear on the tools can result in defects in parts produced. [2]
Unobtainium (or unobtanium) is a term used in fiction, engineering, and common situations for a material ideal for a particular application but impractically difficult or impossible to obtain. Unobtainium originally referred to materials that do not exist at all, but can also be used to describe real materials that are unavailable due to ...
Parapsychologists have conducted hundreds of experiments to determine whether spoon bending is a genuine psychic phenomenon. [4] Physicist John Hasted believed that children could paranormally bend paper clips inside a glass sphere, provided the sphere had a hole in it and they were allowed to take the sphere into a room unobserved.
The flexural strength is stress at failure in bending. It is equal to or slightly larger than the failure stress in tension. Flexural strength, also known as modulus of rupture, or bend strength, or transverse rupture strength is a material property, defined as the stress in a material just before it yields in a flexure test.

The three-point bending flexural test provides values for the modulus of elasticity in bending, flexural stress, flexural strain and the flexural stress–strain response of the material. This test is performed on a universal testing machine (tensile testing machine or tensile tester) with a three-point or four-point bend fixture.
In a recent interview with The Telegraph, Hayley Atwell revealed that her screen test for the mysterious role of Grace in the two-part “Mission: Impossible – Dead Reckoning” required a two ...
[1] [2] [3] Mathematically it is an engineering aspect of geometry. [4] Such is its intricacy in precision sheet metal bending [ 5 ] (with press brakes in particular) that its proper application in engineering has been termed an art.
