In the following scenes, you will learn the basics of Mohr's circle of inertia. A set of inertia values corresponding to a shape will be shown in the upper right corner of the scene. Using these values, you will learn how to:

  • plot Mohr's circle for specified moments and product of inertia
  • calculate the center of Mohr's circle
  • calculate the radius of Mohr's circle
  • determine the maximum and minimum moments of inertia
  • determine the angle from the x axis to the maximum principal axis in Mohr's circle
  • translate the angle found in Mohr's circle to the x-y spatial coordinate system for the shape
