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
Test your knowledge using the equation and check your answer with the calculator..
WR = K * M^2 = ?
