Why hollow rods are used in the manufacture of metal charis tables e.t.c????
i heard that hollow rods are stronger than solid rods ..is it true???? if yes pls explain me the reason friends...
What's a "charis table"?
Off-hand, the hollow rods are probably cheaper and they're undoubtedly lighter. When you're designing a product, you're into engineering, and engineering involves lots of trade-offs, especially at the top or system level. Ultimately, there are three categories: good, fast, and cheap. You can have at most two of those in any product, with rare exceptions.
