A Mechanical Weighing Scale is a type of weighing instrument that operates without the need for electrical or digital components. It uses mechanical mechanisms such as springs or levers to measure the weight of an object. Here's a more in-depth look at how a Mechanical Weighing Scale works.

A spring is the central component in many mechanical scales. When you place an object on the scale, the weight of the object stretches the spring. The more weight on the scale, the more the spring stretches. This stretching is translated into a reading on a dial or pointer that shows the weight. The relationship between the stretch and the weight is calibrated in such a way that it directly correlates to the weight of the object placed on the scale.
