Mohr's Circle for Stress
Mohr's circle is a graphical method used in engineering to represent and analyze the state of stress at a point. It is particularly useful for understanding the relationship between normal and shear stresses acting on a material.
Two Mutually Perpendicular Stresses
To draw Mohr's circle, we need two mutually perpendicular stresses. These can be either normal stresses or shear stresses. The two stresses are plotted as coordinates on a graph, with the normal stress plotted on the x-axis and the shear stress plotted on the y-axis.
Shear Stress
Shear stress is the stress component that acts parallel to a given plane, as opposed to normal stress which acts perpendicular to the plane. In Mohr's circle, two shear stresses are required to construct the circle. These shear stresses can be obtained by applying a shear load to a material and measuring the resulting stresses on two perpendicular planes.
Normal Stress and Shear Stress
Another way to draw Mohr's circle is by using one normal stress and one shear stress. The normal stress is plotted on the x-axis and the shear stress is plotted on the y-axis. This configuration allows us to visualize the relationship between the two types of stresses in a material.
Two Stresses in Two Inclined Planes
The last option, two stresses in two inclined planes, is incorrect. Mohr's circle requires two perpendicular stresses, not two inclined ones. Inclined planes can be used to determine the principal stresses and the orientation of the principal planes, but they are not directly used to construct the circle.
Conclusion
In summary, Mohr's circle for stress requires two mutually perpendicular stresses, which can be either normal stresses or shear stresses. The two stresses are plotted on a graph, with the normal stress on the x-axis and the shear stress on the y-axis. The circle can also be constructed using one normal stress and one shear stress. This graphical method is widely used in engineering to analyze the state of stress at a point and determine important parameters such as principal stresses and maximum shear stress.
