I have a basic question concerning strength and weight of materials. Please forgive me if my question is extraordinarily naive, but I'm an elderly retiree and my education is woefully lacking in this area. Thank you for your patience and understanding.(adsbygoogle = window.adsbygoogle || []).push({});

Let us say we have a block of X material with dimensions 1 x 1 x 1. So it has a cross section of 1 and a volume of 1.

Now, from the same base material, we produce a block with dimensions 2 x 2 x 2. It has a cross section of 4 and a volume of 8.

Would it be correct to say block #2 has a tensile strength 4x greater than block #1, and a weight 8x greater than block #1?

Is there some general rule that states that as an object is scaled up, its weight rises more steeply than its strength?
