Explanation:
When a deforming force is applied to a body in a direction parallel to its surface, it produces a shear strain. Shear strain is the deformation that occurs when one layer of a material slides past another layer. This type of deformation produces shear stress, which is the force that is acting parallel to the surface of the material. Shear stress is calculated as the force per unit area and is expressed in units of pressure, such as pascals (Pa) or pounds per square inch (psi).

Understanding Shear Stress
When a deforming force is applied to a material, it can lead to various types of stress based on the nature of the force and the resulting deformation. Shear stress is one such type that arises when the deformation is characterized by shear strain.
What is Shear Stress?
- Shear stress is defined as the force per unit area acting parallel to the surface of a material.
- It occurs when forces are applied tangentially, causing layers within the material to slide past one another.
Relationship with Shear Strain
- Shear strain is the measure of deformation that occurs in response to shear stress.
- It represents the change in angle between two lines originally at right angles due to the applied shear force.
Why Option A is Correct?
- When a deforming force produces shear strain, the associated stress is specifically termed shear stress.
- Other types of stress, such as longitudinal stress and normal stress, relate to forces acting perpendicular to the surface or along the length of the material, not parallel.
Summary
- In summary, when the deforming force leads to shear strain, it results in shear stress, making option A the correct choice. Understanding this relationship is crucial in fields such as engineering and materials science, where the behavior of materials under various forces is essential.
