The formula to calculate the Crawl Ratio (CR) is:
\[ CR = TR \cdot TCR \cdot AGR \]
Where:
Let's say the transmission ratio (\( TR \)) is 4, the transfer case ratio (\( TCR \)) is 2.5, and the axle gear ratio (\( AGR \)) is 3. Using the formula:
\[ CR = 4 \cdot 2.5 \cdot 3 \]
We get:
\[ CR = 4 \cdot 2.5 \cdot 3 = 30 \]
So, the Crawl Ratio (\( CR \)) is 30.
A crawl ratio is a measure of the number of rotations an engine makes in order to turn a tire one full rotation. It is an important metric in off-road driving, as a higher crawl ratio allows for better control and torque at low speeds, which is essential for navigating difficult terrain.
Definition: Crawl ratio is the ratio of torque at the wheels to the engine flywheel torque.
Formula: \( \text{Crawl Ratio} = \text{TR} \times \text{TCR} \times \text{AGR} \)
Example: \( \text{Crawl Ratio} = 4.0 \times 2.5 \times 3.8 \)
Definition: The Capital Adequacy Ratio (CAR) measures a bank's capital in relation to its risk-weighted assets.
Formula: \( \text{CAR} = \frac{\text{Tier 1 Capital} + \text{Tier 2 Capital}}{\text{Risk-Weighted Assets}} \)
Example: \( \text{CAR} = \frac{500,000 + 300,000}{1,000,000} \)
Definition: The square footage of a crawl space is the total area within the crawl space.
Formula: \( \text{Area} = \text{Length} \times \text{Width} \)
Example: \( \text{Area} = 25 \times 40 \)
