Engine Torque Solution

Follow our step by step solution on how to calculate Engine Torque?

FIRST Step Consider the formula

T = \frac{9.55 \cdot P v}{N}

Next Step Substitute values of Variables

∴

T = \frac{9.55 \cdot 12000W}{6000}

Next Step Prepare to Evaluate

∴

T = \frac{9.55 \cdot 12000}{6000}

Next Step Evaluate

∴

T = 19.1N*m

LAST Step Convert to Output's Unit

∴

T = 19100N*mm
