The forces are equal magnitude but opposite directions act tangent the surfaces of opposite ends of the object
the shear stress as force "f" acting tangent to the surface,dived by the "area"{a}
shear stress=f/a
A shear stress, denoted (tau), is defined as a stress which is applied parallel or tangential to a face of a material, as opposed to a normal stress which is applied perpendicularly.
Shear force is a load (pounds, or newtons) in plane of the object which produces shear stress ( pounds per sq inch, or Pascals).
Shear force is related to shear stress as
STRESS = FORCE/AREA
it is a stress that tears up a layer and made it weak
If you load it normal to the beam axis you get bending stresses ( tension and compression) and shear stresses. If you load it along the axis you get axial stress ( tension or compression)

Tension stress tends to pull a material apart and acts normal to its cross section plane. Shear stress tends to shear a material apart and acts in the plane of its cross section plane. Crushing stress tends to push a material and acts normal to its cross section plane, in the opposite direction of tension. Crushing stresses are compressive stresses and could also be bearing stresses. For a material laoded in pure tension, shear exists at 45 degrees along the cross section plane and is 1/2 the tensile value. For pure shear, tension exists 45 degrees along the cross section plane and is equal to the shear value. Most all metals are stronger in tension than in shear, by a factor of about 1.7. Some materials, like chalk or concrete, are stronger in shear than in tension. If loaded in shear, they will break intension 45 degrees along the cross section
the plane in which three mutually perpendicular stresses act and the resultant of all is purely normal stress . in this plane value of shear stress is zero
That is stress in three dimensions. Biaxial stress is in two dimensions. Triaxial stress has normal and shear stresses along each of three planes. Most beams can be analyzed with uniaxial stress; plates with biaxial; solids with triaxial
If you load it normal to the beam axis you get bending stresses ( tension and compression) and shear stresses. If you load it along the axis you get axial stress ( tension or compression)
Reinforcement designed to resist shear or diagonal tension stresses.
according to bending stress because shear stress at neutral is 0 that is why shear force is maximum
Principal stresses are those stresses that act on principal surface. principal surface here means the surface where components of shear-stress is zero.

Strike slip faults are formed as a result of shear stresses. However strictly speaking all faults are in a shear stress state as there is usually movement in differing directions along both sides of the fault however in the other cases, compressive or tensile stresses are the cause of the initial fault formation.
Compressional stresses (reverse or thrust fault) cause a rock to shorten. Tensional stresses (normal fault) cause a rock to elongate, or pull apart. Shear stresses (strike-slip or horizontal fault) causes rocks to slip past each other.
