Question

140 hp automobile engine delivers only 96hp to the driving wheel. What is the efficiency of the transmission and the drive mechanis

Answer 1

The efficiency of the transmission and the drive mechanics is 68.57%.

Given:

140 hp automobile engine delivers only 96hp to the driving wheel.

To Find:

The efficiency of the transmission and the drive mechanics.

Solution:

To find the efficiency of the transmission and the drive mechanics we will follow the following steps:

As we know,

hp is the horsepower and the large unit of power used to measure power or electrical usage in an office and industries.

It is used to measure the power of engines.

1 hp = 746 watt

Power is the amount of energy dissipated in performing a given amount of work per unit of time.

The unit of power is J/s or watt.

Now,

Efficiency =

$\frac{output \: power}{input \: power} \times 100$

According to the question:

Output power = 96 hp

Input power = 140 hp

Now,

Putting values in the above formula we get,

$efficiency = \frac{96}{140} \times 100 = 68.57\%$

Henceforth, the efficiency of the transmission and the drive mechanics is 68.57%.
