Q: The moment of inertia of a composite body can be calculated using which theorem?
Solution: The moment of inertia of a composite body can be calculated using the parallel axis theorem.
Steps: 5
Step 1: Understand what moment of inertia is. It measures how difficult it is to rotate an object around an axis.
Step 2: Know that a composite body is made up of multiple shapes or objects.
Step 3: Learn about the parallel axis theorem. It states that if you know the moment of inertia of a shape about its own center of mass, you can find the moment of inertia about a different axis parallel to it.
Step 4: Apply the parallel axis theorem to each part of the composite body to find their individual moments of inertia.
Step 5: Add all the individual moments of inertia together to get the total moment of inertia for the composite body.
