An isobar is a curve that joins points of equal-a)Horizontal stressb)...
Explanation:
Isobar is a term used in meteorology to refer to a line on a map connecting points having equal atmospheric pressure. However, in the context of stress analysis, there is no such thing as an isobar.
Stress is a quantity that has both magnitude and direction and is therefore represented by a tensor with nine components. The components of this tensor are usually represented by a matrix with three rows and three columns, and the stress state at a point in a solid body is determined by the values of these components.
There are three types of stress that can be present in a solid body:
1. Normal stress (also called axial stress), which is perpendicular to a surface
2. Shear stress, which is tangential to a surface
3. Hydrostatic stress, which is the same in all directions and represents a change in volume without a change in shape.
None of these types of stress can be represented by an isobar, which is a curve that joins points of equal value of a scalar quantity.
In summary, since stress is not a scalar quantity, it cannot be represented by an isobar. Therefore, the correct answer is D) None of these.
