Moment of inertia

Summary

The moment of inertia of a body about an axis measures how hard it is to change the rotation of the body about that axis. It is the integral of the density times the square of the distance to the axis. So for a solid body it is a triple integral.

What this node needs for W2
  • edge instance_of in: at least two examples (0 of 2)
  • edge not_instance_of in: at least one non-example (0 of 1)
  • edge specializes both: the more general notions and the special cases (0 of 1)

The writing levels say how complete the text of a node is. They do not measure its truth.
