Shearing strain

HOPE that it will help you to understand

Answer 2

The change in the shape of a regular body is due to Shearing Strain.

• Strain is defined as the ratio of the deformation caused by an applied force to the initial dimensions of the body before the application of force.
• This quantity is both unitless and dimensionless.
• Shearing strain is caused due to a shearing (tangential) force.
• Such a force causes an angular deformation in the object let it be Ф.
• Shearing strain is the ratio of the change in dimension (Δx) caused due to the force to the distance between the fixed layer and the point of action of the force (h).

        Shearing strain = Δx / h  = tan Ф
