In this video we explore bending and shear stresses in beams. A bending moment is the resultant of bending stresses, which are normal stresses acting perpendicular to the beam cross-section. We can ...

The hypothesis used in developing the stress and strain in the shaft is that all points on a cross-section of the shaft experience the same angle of twist. The angle of twist for a section of length L ...

Principal stresses are defined as the maximum and minimum normal stresses in a plane. Principal stresses are perpendicular to each other and oriented such that shear stresses are zero. For 3D stress ...

A new study uses shear tests and seepage-stress analysis in north China's Liushagang formation to create a model that predicts collapsing pressure and avoids costly drilling delays in hard, brittle ...

In the above equation, σ 0 is the value of yield stress and η C is the value of Casson viscosity that is related to a high shear rate viscosity. Herschel-Bulkley model is another model used in yield ...

Use your results from the bending moment diagram to determine the location along the length of the beam for the maximum bending moment. Use the flexural stress equation, σ = -My/I, to determine the ...
