Question

Which of the given configurations of Palki (Palanquin) will work the best for the traveller as well as for the labourers carrying the traveller? 

• A. A
• B. B
• C. C
• D. D

Hint:

For design-based questions, always analyze them from the perspective of physics and user experience. Look for features that enhance stability (low center of gravity, wide base) and are practical for the user (in this case, both the traveler and the carriers).

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
The question asks to identify the best design for a palanquin (Palki) considering two factors: comfort and stability for the traveler, and ergonomics and efficiency for the labourers carrying it. This requires applying basic principles of physics (stability, center of gravity) and design.
Step 2: Detailed Explanation:
Let's evaluate each design based on key principles:


Stability for the Traveler: A lower center of gravity increases stability. A wider base of support also prevents tipping. A suspended seat, where the traveler's weight is below the carrying poles, will be much more stable than one where the weight is on top.
Ergonomics for the Labourers: The carrying mechanism should allow the labourers to bear the weight comfortably and efficiently. Straight, parallel poles are easier to carry on the shoulders than angled or complex structures. The weight should be distributed evenly.
Step 3: Analyzing the Options:


(A) and (B): In these designs, the seat is placed on top of the support structure. This creates a high center of gravity, making the palanquin prone to tipping and swaying, which would be uncomfortable and unsafe for the traveler.
(C): This design is superior for several reasons. The seat is suspended below the main carrying poles. This lowers the center of gravity significantly, making the ride very stable. The base is wide, further enhancing stability. The structure provides straight, parallel bars for the labourers to place on their shoulders, which is ergonomically sound for carrying heavy loads over distances.
(D): This design features poles that angle outwards. This is a very poor ergonomic design. It would be extremely awkward for the labourers to carry, as the poles would not rest securely on their shoulders and would force them into an unnatural posture.
Step 4: Final Answer:
Design (C) offers the best combination of stability and comfort for the traveler by having a low center of gravity, and it provides a practical and ergonomic structure for the labourers. Therefore, it is the best design.
