To calculate the rollout:
\[ RO = \frac{D \times \pi \times P}{S \times IR} \]
A rollout is defined as the total distance traveled by a vehicle per one revolution of an engine. It is an important measure in automotive and mechanical engineering, particularly for understanding the performance and efficiency of vehicles.
Let's assume the following values:
Step 1: Multiply the diameter by π and the pinion:
\[ D \times \pi \times P = 30 \times \pi \times 15 = 1413.72 \]
Step 2: Divide the result by the product of the spur and the drive ratio:
\[ RO = \frac{1413.72}{45 \times 3} = 10.51 \text{ inches} \]
Let's assume the following values:
Step 1: Multiply the diameter by π and the pinion:
\[ D \times \pi \times P = 25 \times \pi \times 20 = 1570.80 \]
Step 2: Divide the result by the product of the spur and the drive ratio:
\[ RO = \frac{1570.80}{50 \times 4} = 7.85 \text{ inches} \]
