Definition of Balance Scales
Balance Scales are the set of scales used to measure the weight of the objects.
More About Balance Scales
- There are two equal pans (weighing pans) hanged to a scale at equal distance in a balance scale
- Balance scale contains a beam that tilts towards the pan with more weight. If both the pans have same weight, then the beam remains in a state of equilibrium

Solved Example on Balance Scales
Ques: Jake, while measuring the weight of a watermelon on a balance scale, put weights of 6 lb and found that the pan with the watermelon was tilting slightly down. He again put a weight of 8 oz and found both the pans balanced. What could be the weight of the watermelon?
Choices:
- A. 6 lb
B. 6.5 lb
C. 5 lb
D. 5.6 lb
Correct Answer: B
Solution:
- Step 1: Weight of the watermelon = First weight + Second weight
Step 2: = 6 lb + 8 oz [Given]
Step 3: = 6 lb + 0.5 lb [1 lb = 16 oz]
Step 4: = 6.5 lb [Add]
Step 5: So, the weight of the watermelon is 6.5 lb.
Quick Summary
- Balance scales compare the weight of two objects.
- They use two equal pans to measure weight.
- The beam tilts towards the heavier pan.

Frequently Asked Questions
Q: How do balance scales work?
A: Balance scales work by comparing the weight of an unknown object to a known weight. When the pans are balanced, the weights are equal.
