Question

Which has highest inertia? Solids made up of aluminium, steel or wood of same shape and volume?

Answer 1

1. As we know that the inertia of a body depends upon the mass, the higher the mass higher will be inertia, the lower mass lower the inertia.
2. Thus the mass of the steel is higher than aluminum and wood.

Hence, solids made up of steel of the same shape and volume have the highest inertia.
