There are three solids made up of aluminum, steel and wood, of the same shape and same volume. Which of them would have highest inertia?

Text Solution

Verified by Experts

Out of three solids of same shape and same volume, mass of steel solid is maximum as density of steel is maximim. As mass is a measure of inertia, therefore, steel solid would have highest inertia.
