Question 4 of 5
Efficiency

The efficiency of a machine describes how much of the power put into the machine is turned into movement or force. A 100% efficient machine would turn all of the input power into output movement or force. However, no machine is 100% efficient due to friction, heat, wear and other imperfections that consume input power without delivering any output.

What is the power output of a 5 hp engine that's 80% efficient?
6600 \( \frac{ft⋅lb}{s} \)
2200 \( \frac{ft⋅lb}{s} \)
8800 \( \frac{ft⋅lb}{s} \)
16 \( \frac{ft⋅lb}{s} \)
