## 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.

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