Question

Why are hollow cylinders is stronger than solid cylinders?

Answer 1

Explanation:

Because it is(hallow cylinder) small and thick so its stronger but the solid cylinder is the visa versa

Answer 2

Answer:

Strength to weight ratio is better for a hollow pipe than a solid rod. This means a hollow cylinder is stronger than a rod of equal mass and the same material. A hollow cylinder with a bigger inside diameter is better. Mathematically, the maximum stress directly depends on the polar moment of inertia.
