## Dual Spring Rate Formula

The following two example problems outline the steps and information needed to calculate the Dual Spring Rate.

DSR = (T*B) / (T+B)

- Where DSR is the Dual Spring Rate (N/m)
- T is the top spring rate (N/m)
- B is the bottom spring rate (N/m)

To calculate the duel spring rate, divide the product of the top spring rate and bottom spring rate by the sum of these two rates.

## How to Calculate Dual Spring Rate?

The following example problems outline how to calculate Dual Spring Rate.

Example Problem #1:

- First, determine the top spring rate (N/m).
- The top spring rate (N/m) is given as: 5.

- Next, determine the bottom spring rate (N/m).
- The bottom spring rate (N/m) is provided as: 10.

- Finally, calculate the Dual Spring Rate using the equation above:

DSR = (T*B) / (T+B)

The values provided above are inserted into the equation below and computed.

DSR = (5*10) / (5+10) = 3.33 (N/m)

Example Problem #2:** **

For this problem, the variables required are provided below:

top spring rate (N/m) = 6

bottom spring rate (N/m) = 8

Test your knowledge using the equation and check your answer with the calculator..

DSR = (T*B) / (T+B)** = ?**
