## Wheel Rate Formula

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

WR = K * M^2

- Where WR is the Wheel Rate (lbf/in)
- K is the spring constant (lbf/in)
- M is the motion ratio (lbf/in)

To calculate the wheel rate, multiply the spring constant by the motion ratio squared

## How to Calculate Wheel Rate?

The following example problems outline how to calculate Wheel Rate.

Example Problem #1:

- First, determine the spring constant (lbf/in).
- The spring constant (lbf/in) is given as: 10.

- Next, determine the motion ratio (lbf/in).
- The motion ratio (lbf/in) is provided as: 5.

- Finally, calculate the Wheel Rate using the equation above:

WR = K * M^2

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

WR = 10 * 5^2 = 250.00 (lbf/in)

Example Problem #2:** **

For this problem, the variables required are provided below:

spring constant (lbf/in) = 20

motion ratio (lbf/in) = 4
