Effective Gear Ratio Solution

STEP 0: Pre-Calculation Summary

Formula Used

Effective Gear Ratio = Old Tire Diameter/New Tire Diameter*Gear Ratio of Transmission
G_eff = D′_o/D_n*i_g
This formula uses 4 Variables

Variables Used

Effective Gear Ratio - Effective Gear Ratio is defined as ratio of old tire size to the new tire size and as a result it incorporates the tire size.
Old Tire Diameter - (Measured in Meter) - Old Tire Diameter is defined as the original diameter of the tire before replacing it with a newer one.
New Tire Diameter - (Measured in Meter) - New Tire Diameter is defined as the diameter of the tire which replaces the old tire of the vehicle.
Gear Ratio of Transmission - Gear Ratio of Transmission is the ratio between the revolutions of the engine crankshaft and the revolutions of the shaft which comes out of the gearbox.

STEP 1: Convert Input(s) to Base Unit

Old Tire Diameter: 0.71 Meter --> 0.71 Meter No Conversion Required
New Tire Diameter: 0.66 Meter --> 0.66 Meter No Conversion Required
Gear Ratio of Transmission: 2.55 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

G_eff = D′_o/D_n*i_g --> 0.71/0.66*2.55

Evaluating ... ...

G_eff = 2.74318181818182

STEP 3: Convert Result to Output's Unit

2.74318181818182 --> No Conversion Required

FINAL ANSWER

2.74318181818182 ≈ 2.743182 <-- Effective Gear Ratio
