How to calculate the shear force of steel ball

1.

Shear force F (n) = sectional area s (mm 2) x yield strength σ "Shear" is a relative dislocation deformation phenomenon of the cross section of the material under the action of a pair of lateral external forces (that is, the force perpendicular to the action surface) which are very close, the same size and opposite to each other. The force that can make the material proce shear deformation is called shear force or shear force

extended data:

the key to judge whether "shear" or not is whether the cross section of material has relative dislocation. Therefore, cutting vegetables with a kitchen knife is not a shearing phenomenon (because there is no relative dislocation in the cross section of vegetables), while cutting nails with scissors is a shearing phenomenon (relative dislocation in the cross section of nails). Note: using nail clippers to cut nails is not a cutting phenomenon, although it can also cut nails off. It belongs to extrusion deformation

As for the source of "shear force", it is of course caused by pressure. It can also be said that shear force is a special form of pressure

2. Shear stress should be calculated before shear force τ( It's the shear force per unit area τ = DF / DS), and then look at the position of the part you want to study, and then integrate and calculate the shear force. Draw the shear diagram, that is, the shear force on each part of the steel pipe, which can be deced from the stress of the steel pipe. Then, the stress area (perpendicular to the direction of the shear force) is calculated at the position where the shear stress needs to be calculated, and the shear force is divided by the stress area

shear force: shear stress, or shear force, where y is the temperature and concentration of the solution, the properties of the solvent, and the gradient of polymer forming velocity in the solution, or shear rate.

3. This can check the tensile strength of the material from the mechanical design manual, and then calculate the shear stress according to the empirical formula (in the manual), and then take a certain safety factor to determine the required force, and then determine the power of the oil pump. I don't have a manual now. I can't tell you the formula. You can check it yourself.
