Gear Ratio Acceleration Calculator









Understanding the relationship between gear ratio and acceleration is critical for optimizing vehicle performance. The Gear Ratio Acceleration Calculator allows you to quickly compute the acceleration produced by a specific gear ratio and input acceleration, making it invaluable for automotive enthusiasts and engineers.

Formula

The formula to calculate gear ratio acceleration (GRA) is:
GRA = GR × IA

Where:

  • GRA is the gear ratio acceleration in meters per second squared (m/s²).
  • GR is the gear ratio.
  • IA is the input acceleration in meters per second squared (m/s²).

How to Use

  1. Enter the gear ratio (GR).
  2. Input the initial acceleration (IA) in meters per second squared.
  3. Click the “Calculate” button.
  4. The gear ratio acceleration (GRA) will be displayed in the result field.

Example

Suppose a vehicle has:

  • Gear Ratio (GR) = 3.5
  • Input Acceleration (IA) = 2.0 m/s²

Using the formula:
GRA = GR × IA
GRA = 3.5 × 2.0 = 7.0 m/s²

The gear ratio acceleration is 7.0 m/s².
