Question

With regard to stress from mechanical loading, the term shearing refers to

a) Compression forces
b) Tension forces
c) Sliding forces
d) Twisting forces

Answer 1

Option C.

Shearing refers to sliding forces that cause deformation by shifting layers parallel to the surface, distinct from compression, tension, or twisting forces.

Step-by-step explanation:

With regard to stress from mechanical loading, the term shearing refers to forces that act parallel to the surface, resulting in sliding layers on top of one another without changing the volume of the material.

This type of force is different from compression forces that squeeze an object, tension forces that stretch an object, and twisting forces that rotate an object around its axis.

Therefore, in the context of mechanical stress, shearing corresponds to sliding forces, which is option c).

Shear stress causes shear strain, characterized by a shift of layers in the direction tangent to the applied forces, quantified by the shear modulus.

The correct option in the final answer is c) Sliding forces.
