Mohr's circle is a graphical representation of plane stress problems showing Correct Answer maximum shear stress

Explanation:

Mohr's circle:

  • Mohr's circle diagram is a representation of the normal stress component σ are plotted on the horizontal axis while the shear stress component τ are plotted on the vertical axis.
  • Tensile normal stresses are plotted along the positive σ-axis, that is, to the right of the τ-axis, while compressive normal stresses are plotted to the left of the τ-axis.
  • Shear stress components that produce clockwise rotation of an infinitesimal element around the point P under consideration.

The objective of drawing mohr's circle that we could find

  • Construct Mohr's circle with different values of σx, σy, and τxy
  • Locate σ1, σ2, and τmax on Mohr's circle
  • Calculate principal stresses and maximum shear stress
  • Calculate the orientation of principal planes and the maximum shear stress plane.
  • Analyze the changes on a real stress element as its angle changes dynamically.
