It doesn't typically provide a specific weight in grams or ounces, but rather indicates which item is heavier, lighter, or if they are equal. A (or beam balance) is a simple machine

It works on the principle of a lever, where two pans hang on opposite sides of a pivot point (fulcrum). If both sides are empty, or contain equal weights, the scale remains level. It doesn't typically provide a specific weight in

It consists of a beam, a pointer, a fulcrum, and two pans. 2. Simple DIY Balance Scale (For STEM/Kids)
