ANS:A - uniform strength in all directions.

Uniform strength in all directions refers to the mechanical property of a material where its strength remains consistent, regardless of the direction in which it is loaded or stressed. In other words, the material exhibits isotropic mechanical behavior, meaning its properties are the same in all directions. For materials with uniform strength in all directions, the response to applied loads is consistent, whether the load is applied along one axis, at an angle, or in any other direction. This property is desirable in many engineering applications where the material needs to withstand stresses from various directions. However, wrought iron does not possess uniform strength in all directions. Instead, its mechanical properties can vary depending on the direction of the applied load. This anisotropic behavior is typical of many materials, including wrought iron, and must be considered in engineering design and analysis.
