Enter the weight on the left side and the weight on the right side into the calculator to determine the balance factor. This calculator helps in assessing the symmetry of a load distribution.

## Balance Factor Formula

The following formula is used to calculate the balance factor:

BF = (LW - RW) / (LW + RW)

Variables:

• BF is the balance factor
• LW is the weight on the left side (kg)
• RW is the weight on the right side (kg)

To calculate the balance factor, subtract the right weight from the left weight and divide the result by the sum of the left weight and the right weight.

## What is a Balance Factor?

The balance factor is a dimensionless value that indicates the symmetry of weight distribution between two sides. It is commonly used in various fields such as mechanical engineering, physical therapy, and ergonomics to ensure that loads are evenly distributed or to assess the balance of an individual or object. A balance factor of zero indicates perfect balance, while positive or negative values indicate a heavier load on the left or right side, respectively.

## How to Calculate Balance Factor?

The following steps outline how to calculate the Balance Factor.

1. First, determine the weight on the left side (LW) in kilograms.
2. Next, determine the weight on the right side (RW) in kilograms.
3. Use the formula from above = BF = (LW – RW) / (LW + RW).
4. Finally, calculate the Balance Factor (BF).
5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Left Weight (LW) = 50 kg

Right Weight (RW) = 45 kg
