I found this problem in a book and am trying to answer it by myself. 1. Can you think of a body that has the same moment of inertia for all possible axes? If so, give an example, and if not, explain why this is not possible. Solution: I can't think of any example or disprove the hypothesis. So I am wondering how I can answer this part. 2. Can you think of a body that has the same moment of inertia for all axes passing through a certain point? If so, give an example and indicate where the point is located. Solution: An example is a solid sphere, with the point located at its centre. What do you think?
