Answer:
The efficiency of the transmission and drive mechanism is 67.5%
Step-by-step explanation:
for a 120 hp automobile engine which delivers only 81 hp, we have the efficiency of transmission to be;
[tex]\frac{81}{120}[/tex] × 100
= [tex]\frac{81 * 100}{120}[/tex]
= [tex]\frac{8100}{120}[/tex]
= [tex]\frac{810}{12}[/tex]
= 67.5%
