Rollout Calculator









Formula

To calculate the rollout:

\[ RO = \frac{D \times \pi \times P}{S \times IR} \]

What is a Rollout?

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.

Example Calculation 1

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:

\[ RO = \frac{1413.72}{45 \times 3} = 10.51 \text{ inches} \]

Example Calculation 2

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:

\[ RO = \frac{1570.80}{50 \times 4} = 7.85 \text{ inches} \]
