The efficiency of four basic modes of human power output varies as per the following:
Show Hint
Remember: Cranking is the most efficient human power mode.
Pulling is the least efficient.
Pulling is the least efficient.
Updated On: Aug 18, 2026
- Cranking > Pedaling > Pushing > Pulling
- Pulling > Pushing > Cranking > Pedaling
- Pushing > Pedaling > Pulling > Cranking
- Pedaling > Pulling > Pushing > Cranking
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Human power output efficiency varies for different activities.
We need to arrange them in decreasing order of efficiency.
Step 2: Key Formula or Approach:
No specific formula.
Need to know the relative efficiencies.
Step 3: Detailed Explanation:
Cranking has the highest efficiency among human power modes.
Pedaling is the next most efficient.
Pushing is less efficient than pedaling.
Pulling is the least efficient among these.
Thus, the order is: Cranking > Pedaling > Pushing > Pulling.
Step 4: Final Answer:
The correct order is Cranking > Pedaling > Pushing > Pulling.
Hence, the correct option is (A).
