1.4. Mohr’s circle

Try these first

1. 1.

   What do you represent on the horizontal axis of Mohr's Circle?

   Hint

   Think about the types of strain we discussed.

2. 2.

   What does the radius of Mohr's Circle represent?

   Hint

   Relate this to how we derived the circle.

3. 3.

   What is plotted on the vertical axis of Mohr's Circle?

   • Normal Strain
   • Shear Strain
   • Principal Strain

   Hint

   Remember the axes discussed in the lesson.

4. 4.

   True or False: The radius of Mohr’s Circle directly gives you the maximum shear strain.

   • True
   • False

   Hint

   Consider the relationship of the radius in our discussion.

5. 5.

   Given three-dimensional strain capture with given values for longitudinal and shear strains, calculate the exact positioning of Mohr's Circle in 3D and project it onto a 2D plane.

   Hint

   Visualize and utilize the relationships in 3D space.

6. 6.

   Examine the effect of varied loading cases on Mohr's Circle by changing the original strain values and observing directional shifts in principal strain components.

   Hint

   Consider drawing transitions of the circle as loads change direction.
