One manpower is considered equal to how much horsepower (hp)?
A
0.5
B
0.4
C
0.2
D
0.1
Correct Option:
D
Explanation
For conventional engineering estimates, sustained human power is often taken as roughly 75 watts. Since 1 horsepower is about 746 watts, 75/746 ≈ 0.10 hp. Hence one “manpower” is approximately 0.1 hp.
