Shear strain is the components of a strain at a point that produce changes in shape of a body (distortion) without a volumetric change. That is, the tangent of the angular change in orientation of two initially perpendicular lines . Approximately equal in magnitude to the angle itself in radians for infinitesimal strains.
We knew from Hook's law- "stress is proportional to strain." So, stress = k * strain [here, k is a constant] or, stress/strain= k Now, if the stress and strain occurs due to axial force then k is known as modulus of elasticity and it is denoted by E. if the stress and strain occurs due to shear force then k is known as modulus of rigidity and it is denoted by G.
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

There are 6 vectors used to describe the strain field of an element. An equivalent strain is just a single numerical value used to represent the strain field.

It is the ratio of shear stress to shear strain.
Hooke's Law in shear states that the shear stress in a material is directly proportional to the shear strain applied, as long as the material remains within its elastic limit. This relationship is expressed mathematically as τ = Gγ, where τ is the shear stress, G is the shear modulus, and γ is the shear strain.
Simple shear strain involves deformation by parallel sliding of fabric layers in opposite directions, resulting in stretching and compressing of the material. Pure shear strain occurs when fabric layers are displaced in opposite directions, causing the material to deform by shear without any change in volume. In simple shear, there is both shearing and stretching/compressing, while in pure shear, only shearing occurs.
Robert Hooke in 1660 discovered the stress strain relation known as Hooke's law. The shear tress relation ( stress = rigidity modulus x shear strain) is a logical extension of Hooke's law,
The three types of strain are tensile strain, compressive strain, and shear strain. Tensile strain occurs when an object is stretched, compressive strain occurs when an object is compressed, and shear strain occurs when two parts of an object slide past each other in opposite directions.
The normal strain is a deformation caused by normal forces such as Tension or Compression that act perpendicular to the cross-sectional area, while the shear strain is a deformation obtained from forces acting parallel or tangential to the cross-sectional area.

Shear Stress divided by the Angle of Shear is equals to Shear Stress divided by Shear Strain which is also equals to a constant value known as the Shear Modulus. Shear Modulus is determined by the material of the object.
hi .. this Q I have asked you to answer it ..... how can I answer it if I have knowing the answer so why I aske you to answer me ...
No, it is not. Shear can be a verb (to cut, remove wool, or to apply force at an angle) or a noun (cutting tool, shearing force). It can, however, be a noun adjunct in terms such as shear strain. *Not to be confused with the homophone "sheer" - adjective meaning transparent.
Strain shows how much longer a beam becomes after applying a force in a chosen direction.Strain = change of length of the the beam / original length of the beamIn case of Shear Strain force is applied only parallel to the surface of the beam (not normal to it).The same principal can be applied not only to beams, but to other civil engineering components as well.
