A mechanical scale is a device used to measure weight without the need for electricity. It typically consists of a platform where an object is placed, and a dial or beam that shows the weight. When you put something on the platform, the scale uses springs or levers to determine how heavy the object is, providing a reading in units like pounds or kilograms. These scales are often found in homes, gyms, and doctor's offices. Unlike digital scales, which require batteries, mechanical scales are simple and reliable. They are also easy to use, making them a popular choice for everyday weight measurement.
