Question

Identify the correct mechanism that enlarges the blue fish to red when traced with the blue dot. 

• A. A
• B. B
• C. C
• D. D

Hint:

To identify scaling mechanisms, look for configurations that maintain proportional relationships between corresponding points during motion.

Answer 1

The Correct Option is C

1. The correct mechanism for scaling the blue fish to the red fish involves a proportional linkage system that traces and enlarges the shape.
2. Option A: The linkage configuration in \(A\) does not provide the necessary proportional scaling for accurate enlargement.
3. Option B: The structure in \(B\) does not maintain proportional alignment for the traced enlargement.
4. Option C: The mechanism in \(C\) includes a parallelogram linkage that ensures proportional scaling and tracing, making it the correct option.
5. Option D: The configuration in \(D\) introduces distortions and does not correctly scale the shape proportionally.
Conclusion: The mechanism that enlarges the blue fish to the red fish is \(C\).
