say fonz you are not paying attention, by now you should know that every vertical shear stress VQ/It in the xy plane is accompanied by a longitudinal equal stress in the z direction in the xz plane.fonseh said:
Shear stress is a type of stress that occurs when two surfaces of an object slide against each other in opposite directions.
Normal stress occurs when a force is applied perpendicular to the surface of an object, while shear stress occurs when a force is applied parallel to the surface.
Shear stress is typically measured in units of force per area, such as pounds per square inch (psi) or newtons per square meter (N/m²).
The direction of shear stress is affected by the orientation and shape of the object, as well as the magnitude and direction of the applied force.
Shear stress plays a crucial role in the strength and stability of materials, as it can cause deformation or failure in structures and components. Understanding and controlling shear stress is essential in designing and constructing safe and durable structures.
