Question

A 240hp automobile engine delivers 195hp to the drive wheels, what is the effciency of the transmission and drive mechanism?

Answer 1

81.25%

Explanation:

Given that :

Engine power = 240 hp

Power delivered to drive wheel = 195 hp

Efficiency = (power delivered to drive wheel / Engine power) * 100%

Efficiency = (195 / 240) * 100%

Efficiency = 0.8125 * 100%

Efficiency = 81.25%

The efficiency of transmission and drive mechanism is 81.25%
