The brake lever ratio is a measure of the mechanical advantage provided by a brake lever. It is the ratio of the lever length to the pivot distance. A higher ratio means more force is applied to the brake with less effort, while a lower ratio means more effort is needed to apply the same amount of force. This ratio is crucial in designing brake systems for bicycles, motorcycles, and other vehicles to ensure optimal performance and safety.
The formula to calculate the brake lever ratio is:
\[ \text{R} = \frac{\text{L}}{\text{P}} \]
Where:
Let's assume the following values:
Using the formula:
\[ \text{R} = \frac{100}{20} = 5 \]
The brake lever ratio is 5.
