mechanical scales
Mechanical scales are devices used to measure weight without the need for electricity. They typically consist of a platform where you place the object you want to weigh, along with a system of springs and levers that translate the weight into a readable measurement. These scales are often found in homes, kitchens, and even at farmer's markets for weighing produce.
One common type of mechanical scale is the spring scale, which uses a spring to determine weight. As you add weight to the platform, the spring stretches, and the scale's dial or pointer moves to indicate the weight. Mechanical scales are simple, reliable, and do not require batteries, making them a practical choice for many users.
