Question

How is shear obtained?

Expert Solution

Step 1

Shear stress developed in material obtains from the applied force on the material and the structure's cross-sectional area. The applied force and the cross-sectional area of the element are parallel to each other. When a shear force is applied parallel to the material, the top part of the material slides from the initial position, but the bottom part remains the same. The word shear means to tear off or to remove the part.

The formula to obtain shear stress on the material is given by:

Here, F_ext is the external force on the surface.

A is the cross sectional area.
