(A) deformation (B) formation
(C) contraction (D) strain.​

Answer 1

Change in dimensions is known as....

(A) deformation

Answer 2

The correct answer is option (a) deformation.

• Deformation is defined as the change in size or shape of an object. Deletion is a complete change in place of a point in an object. The deviation is a change related to the external removal of an object.
• Strain is a relative internal change in the shape of an infinitely smaller cube material and can be expressed as a non-dimensional change in length or angle of cube distortion.
• Strains related to the force acting on a cube, known as pressure, are a stress-strain curve. The relationship between stress and stress is usually straightforward and reversed until the harvest is over and the decline is expanding. The key line relationships are known as Young's modulus. Above the production point, a certain degree of permanent deformation remains after pouring and is called plastic decay.
