Spring Balance Newton Meter

A Spring Balance is a simple instrument used to measure force, weight, or tension based on the principle of Hooke’s Law, which states that the force applied to a spring is proportional to its extension. Spring balances are commonly used in classrooms, laboratories, and in various applications that require measurement of small forces or weights.

1. Measuring Capacity:

• Weight Range (Maximum Capacity): Typically, spring balances are available in a range of capacities, such as:
  • 50g, 100g, 200g, 500g, 1000g , or higher, depending on the intended use.
  • For example, a 100g Spring Balance can measure up to 100 grams (0.1 kg) or approximately 1 Newton of force under Earth’s gravity.

2. Graduation (Scale Increments):

• Graduation (Divisions): The scale is divided into smaller units, typically 1g, 2g, 5g, 10g, depending on the total range of the balance.
  • Higher precision models may have 0.5g or 1g divisions.
  • The scale might be in grams (g) for weight measurement or Newtons (N) for force measurement.
• Accuracy/Tolerance: The accuracy is often ±1 division, meaning it can be off by 1g or so in measurements. More precise models might have a tolerance of ±0.5g.

3. Units of Measurement:

• Grams (g): Most spring balances are designed to measure weight or force in grams.
• Newtons (N): For measuring force directly, some spring balances include both grams and newtons on the same scale.
  • 1 Newton is approximately equal to 100 grams under Earth’s gravity.

4. Spring Material:

• High-Quality Steel: The spring in a spring balance is typically made from stainless steel or carbon steel to ensure durability, consistent elasticity, and minimal rusting or corrosion.
• Plastic Casing: The body is typically made of durable plastic
