Enter the distance between the extreme of any group of 2 or more consecutive axles (in) and the number of axles in the group into the Bridge Weight Calculator. The calculator will evaluate the Bridge Weight.

## Bridge Weight Formula

The following two example problems outline the steps and information needed to calculate the Bridge Weight.

BW = 500* (L*N/(N-1) + 12*N + 36)

Variables:

• BW is the Bridge Weight (lbs)
• L is the distance between the extreme of any group of 2 or more consecutive axles (in)
• N is the number of axles in the group

## How to Calculate Bridge Weight?

The following steps outline how to calculate the Bridge Weight.

1. First, determine the distance between the extreme of any group of 2 or more consecutive axles (in).
2. Next, determine the number of axles in the group.
3. Next, gather the formula from above = BW = 500* (L*N/(N-1) + 12*N + 36).
4. Finally, calculate the Bridge Weight.
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.

distance between the extreme of any group of 2 or more consecutive axles (in) = 50

number of axles in the group = 4

BW = 500* (L*N/(N-1) + 12*N + 36) = ?
